Aluminum Foil for Induction Sealing

In the packaging industry, the production process is determined by the product dosage form, but the packaging link occupies a large proportion. Packaging plays an extremely important role in product quality assurance, and there are many types of materials used in packaging.

Among them, due to its good mechanical properties, barrier properties, safety properties, and its superior processing properties, aluminum foil for induction sealing has good sealing properties, excellent freshness retention and light shielding properties, which can prevent oxidative deterioration of products.

Its sealing can ensure a tight, smooth and easy-to-tear effect. It can also improve the advertising effect and product value through printing technology. Therefore it is widely used in the packaging industry.

The technical principle of aluminum foil sealing is to heat the aluminum foil sealing gasket through electromagnetic waves, so that the heat sealing layer of the aluminum foil sealing gasket is heated and melted, and the heat sealing layer is bonded to the bottle mouth under certain pressure conditions, thereby achieving a rapid non-contact air seal.

Aluminum foil’s compatibility with heat-seal paint, coupled with the metal’s excellent thermal conductivity and stability, make it an ideal material for capping and heat-sealing a variety of plastic milk containers. Whether the milk is fresh, aseptically filled or sterilized in containers, foil/coating combinations can be designed to meet processing and distribution needs.

The heat sealing aluminum foil alloys are usually 8011 aluminum foil and 8079 aluminum foil. The 8 series heat sealing foil has fewer holes, good barrier and heat sealing properties, and the product is clean of oil and has a clean surface. The aluminum foils reach ood grade, which can be steamed at high temperatures, and is hygienic.

The aluminum foil is the carrier of the adhesive layer, and its quality has a great influence on the heat sealing strength of the product. Especially the oil on the surface of the original aluminum foil will weaken the bonding force between the adhesive and the original aluminum foil. If there is oil on the surface of the original aluminum foil and the surface tension is lower than 31×10-3μm, it will be difficult to achieve the ideal heat sealing strength, so the quality of the aluminum foil must be strictly controlled.

Why Is Prepainted Aluminum Used for Bottle Cap

Bottle caps are essential for sealing all kinds of containers. Food and drinks are therefore optimally protected throughout their shelf life. One of the main bottle cap materials is the prepainted aluminum.

The painted aluminum sheet refers to an aluminum coil that is processed into aluminum sheets, then surface processed and coated with one or several layers of organic coatings such as polyester, fluorocarbon polyester, and then baked and solidified.

After the aluminum coil is coated, the paint covers its surface to form a firmly adherent continuous coating with corrosion resistance, which isolates the aluminum coil base from the corrosive medium, thereby preventing or slowing down damage caused by corrosion.

By using the diversity of paint colors and painting techniques, aluminum sheet can be painted to obtain decorative coatings of different colors, glosses, etc., making their appearance bright and dazzling, or rich in tone, which gives people a pleasing feeling, thereby increasing the added value of the product and expanding the application scope of the aluminum sheet.

Since the middle of the last century, the roller coating has been the main method. The production of color-coated aluminum coils is carried out by a precision coating machine evenly coating the surface of the pre-treated aluminum coils with the same thickness, entering the oven with an exhaust device at a constant speed, and using infrared or hot air circulation baking processes to bake and solidify.

Roller coating uses the coating roller as the carrier of the paint. The paint forms a wet film of a certain thickness on the surface of the coating roller. The coating roller contacts the object to be coated during rotation, and the paint is applied to the surface of the object to be coated.

Roller coating is suitable for coating flat metal plates, especially for high-speed coating of metal coils. Roller coating has the characteristics of fast coating speed, high production efficiency, and 100% paint utilization rate.

As one of the big painted aluminum sheet metal suppliers, the coating Haomei Aluminum chooses is of food grade and doesn’t contain BPA. It also has good adhesion and can withstand the test of high-temperature cooking. Welcome to leave message below to inquire what you need.

What Are The Advantages of ACP Sheet

ACP(aluminum composite sheet) is a new material that uses aluminum honeycomb core or foamed aluminum or solid aluminum plate as the base material, and composites PVC, PET film, solid wood skin, stone, cloth, leather and other common finishes on the surface of the solid aluminum plate like pre painted aluminium coil. What are its advantages?

1. Lightweight and high strength

Composite aluminum panels are made of aluminum and other metal or non-metal materials and are lightweight and high-strength. The low density of aluminum makes the overall weight of composite aluminum panels lighter and easier to handle and install. At the same time, the composite process can make it have higher strength and be able to withstand greater pressure and impact.

2. Corrosion resistance

Aluminum has good corrosion resistance and can be used for a long time in most environments without being affected by corrosion. Composite aluminum plates further increase their corrosion resistance on the basis of aluminum, making them more suitable for harsh external environments, such as marine environments.

3. Weather resistance

Composite aluminum panels have good weather resistance and can withstand erosion from the sun, rain, wind and other natural environments. Its surface has been specially treated so that it is not susceptible to discoloration, fading, etc. caused by ultraviolet rays, and can maintain its long-term beauty.

Why Is Duralumin Used in Aircraft?

“Large aircraft” generally refers to transport aircraft with a total take-off weight exceeding 100 t, including military and civilian large transport aircraft, as well as trunk airliners with more than 150 seats. Aluminum alloys have low density, high specific strength, strong corrosion resistance, and easy thermal conductivity. It has a series of advantages such as good plasticity and processing performance, low cost, etc., and has always been the main material for the structure of large aircraft in aviation.

The traditional aluminum alloys for large aircraft structures are mainly high-strength 2000 series((2024, 2224, 2324, 2424, 2524, etc.) and ultra-high-strength 7000 series(matweb aluminum 7075, 7475, 7050, 7150, 7055 , 7085, etc.) After the 1980s, although there was aluminum lithium alloy, rapid solidification aluminum alloy, composite materials, the traditional 2000 and 7000 aluminum alloys still show strong vitality.

7075 aluminum alloy is a high-strength, heat-treatable wrought alloy developed by Alcoa in 1943. The alloy contains zinc, magnesium, chromium and copper as hardeners, as well as small amounts of iron, silicon, manganese and titanium. Al-7075 is much stronger than carbon steel after heat treatment. The common tempers are 7075-T6, T651, T7351, T73, T76, T7651, O, W, W51, etc.

The success of the 7150-T77 aluminum not only meets the requirements of corrosion performance, but also does not sacrifice the strength of the alloy. Later, by adjusting the alloy composition, reducing the content of impurity elements such as Fe and Si, and improving the production process, Alcoa developed the 7055-T77 ultra-high strength plate and the 2524-T3 ultra-high fatigue strength plate.

2024 aircraft aluminum alloy is a typical hard aluminum alloy in the aluminum-copper-magnesium system, whose composition is more effective. What are the al 2024 properties? It has high strength and certain temperature resistance, and can be used as a working part below 150 degrees. After heat treatment, the 2024 aluminum alloy has undergone solid solution treatment to obtain relatively high compressive strength and ductility. Because its strength is very high, it is generally used to produce skins, roof beams, bulkheads, and wings by plane.

The fracture toughness and fatigue resistance of 2524-T3 clad aluminum plate are more than 30% higher than that of 2024-T3 clad aluminum plate, and it is considered to be the most ideal aircraft skin material at present. The strength of 7055-T77 alloy is 25% higher than 7075-T651 and 8~12% higher than 7150-T77, while the fracture toughness and stress corrosion resistance are comparable to 7050-T61.

What Parts Of a Car Are Aluminum

The body-in-white is connected by stamping parts of different sizes through welding or other processing methods. Different materials are used for each part according to the needs. Different materials have a decisive effect on the stamping process. So first of all, what materials are used in the body in white?

1. Steel: Needless to say, most of the cars on the market are still mainly made of steel body, which is the most mainstream body material.

2. Aluminum: The density of aluminum is about one third of that of steel. Due to the demand for lightweight, more and more car manufacturers have begun to consider aluminum body solutions. The traditional car brands that respect the application of aluminum materials in the body mainly include Audi, Jagua, TESLA and NIO.

What parts of a car is aluminum? Before answering this question, there are two concepts we need to know first.

Strength

Strength is divided into yield strength and tensile strength. To put it simply, the yield strength is the strength when the material begins to deform irreversibly (for example, the pipe is bent and cannot be straightened), which characterizes the ability of the material to resist deformation.

Tensile strength refers to the strength of the material when it is broken (the pipe is broken), which characterizes the ability of the material to resist damage. In general, the tensile strength is always greater than the yield strength.

Ductility

A physical quantity that expresses the deformation ability of a material.

The strength of steel for bodywork covers a huge range from 200 megapascal (MPa) to the highest 2000 MPa. We call steels with a tensile strength above 500 MPa AHSS. The performance of different steel plates is too different, so the safety of the car cannot be measured only by the thickness of the steel plate.

At present, 5, 6, and 7 series aluminum sheets are mostly used on the car body. Among them, the 5000 series aluminum like 5182 aluminum body panel is for the interior plate of car door or hood panel. The outer panel of doors, engine covers, and side panel generally choose 6000 series. The 7 series is regarded as a high-strength material among aluminum alloys, and its tensile strength is generally 500 MPa, which is already the limit of aluminum.

Compared with the steel just mentioned above, it is basically the entry-level level of advanced high-strength steel. However, the natural advantage of aluminum is its low density, which is only one-third of that of steel. Under the same volume, the weight is only one-third of that of steel, so it still has a lot of room for use in the car lightweight.

The most important thing for the selection of automotive materials is safety in the face of collisions. For crash safety, the body can be divided into two main areas: the energy-absorbing area and the safety area.

Different regions have very different requirements for materials. For example, the main function of the front and rear parts of a car including front and rear longitudinal beams require is energy absorption for impacts from the front and rear. The area enclosed by strength and deformation can be roughly considered as the material’s ability to absorb energy.

Of course, we don’t want these energy-absorbing parts to break prematurely during the collision, so a certain elongation is the basic requirement for these parts. The second need is strength. Proper strength and good deformability are the requirements for these parts. 6000 and 7000 series aluminum like 6016 aluminum plate are used.

AIWAYS U5 adopts a body structure of upper body steel and lower body aluminum. At the front end of the lower body as the energy absorption area, different materials such as 5, 6, 7 series aluminum plates, cast aluminum, extruded aluminum, etc. are used to maximize the function of energy absorption.

Why Is 5083 Aluminum Sheet Used for Fuel Tanker

At present, the widely used tank body materials of oil tankers include carbon steel, stainless steel and aluminum sheet, each of which has its own advantages. In recent years, with the introduction of the concept of lightweight, more and more manufacturers choose aluminum alloy as the tank material. The main alloy grades are 5083, 5754, 5454, 5182 and 5059. Today we focus on the requirements of the tank body material of the tanker and the advantages of the aw 5083 aluminium.

Since the aluminum alloy tanker is lighter than the carbon steel tanker, the fuel consumption during transportation is reduced. When the no-load driving speed is 40 km/h, 60 km/h and 80 km/h, the fuel consumption of the aluminum alloy tank is 12.1%, 10% and 7.9% lower than that of the carbon steel tank, thereby reducing daily operating costs. Aluminum alloy semi-trailer tank truck can reduce tire wear due to its light weight, thereby reducing vehicle maintenance costs.

Oil tanks for transporting aviation gasoline and jet kerosene must be welded with aluminum alloy, because even if stainless steel tanks are used, a very small amount of iron will enter the oil, which is not allowed.

The 16t oil tank truck developed by Mitsubishi Motors Corporation of Japan, except that the tank is welded with aluminum alloy plates, its frame (11210mm×940mm×300mm) is made of aluminum alloy profiles, which is 320kg lighter than the steel frame. The 16t oil tank truck developed by Mitsubishi Motors Corporation of Japan, except that the tank is welded with aluminum alloy plates, its frame (11210mm×940mm×300mm) is made of aluminum alloy profiles, which is 320kg lighter than the steel frame.

The cross-section of the cylinder is a circular arc rectangle, which is based on the consideration of lowering the center of gravity of the vehicle and increasing the cross-sectional area within the range of vehicle dimensions. It is welded with 5083 alloy and the thickness of the plate is 5mm~6mm. The material of the baffle and the head is the same as that of the tank body, which is also 5083 alloy.

The wall thickness of the head is equal to or greater than that of the tank body plate, the thickness of the baffle and bulkhead is 1mm thinner than that of the tank body, and the thickness of the left and right support plates at the bottom of the tank body is 6mm~8mm, and the material is 5A06.

Advantages of 5083 aluminum plate for tanker body

1. High strength. It is not easy to deform. EN 5083 aluminium has high strength, especially high fatigue resistance, high plasticity and corrosion resistance.

2. Good corrosion resistance and long service life. 5083 aluminum plate contains magnesium element, which has good forming performance, corrosion resistance and weldability. It can meet the corrosion resistance requirements of tank car body materials and has a long service life.

3. Good fire resistance and high safety. In the event of strong impact, the tank weld is not easy to crack.

4. Good environmental protection and high recycling rate. Carbon steel materials cannot be recycled and can only be treated as scrap iron, while aluminum alloy tanks can be recycled and reused, and the recycling price is also high.
