What Is Aluminium Foil Thickness

The aluminum foil thickness is usually below 0.2 mm. It can be divided into light gauge aluminum foil and heavy duty aluminum foil. The light gauge foil is less than 0.1mm, usually 0.0004 thick and 0.0007 thick. It is widely used in beverage packaging, flexible packaging, cigarette packaging, capacitors and construction and other fields.

Most aluminum foils belong to the light gauge foil like medicine packaging foil, tape foil, food packaging foil,electronic foil. How to choose aluminum foil thickness? It is necessary to determine the use of the light gauge foils, as well as the requirements for specifications, surface quality and performance of aluminum foil. For example, the aluminum foil used in architectural decoration needs to have a smooth and beautiful surface, so it is best to have no oil stains and water spots.

As the name implies, heavy duty aluminum foil is thicker and sturdier than regular aluminum foil. It’s tough enough to stand up to high heat, heavy food items, and long-term storage in the freezer. The heavy duty aluminum foil thickness is between 0.008-0.001 thick.

How to measure the values

Use a ruler to measure the length and width of the aluminum foil in centimeters. Crumple the piece of foil into a small ball or fold it into a small shape and place it on a milligram balance to find the weight. Records the values on a sheet of paper or data table.

Control the thickness difference of aluminum foil

It is a feature of aluminum foil rolling that thickness deviation is difficult to control. The thickness difference of 3% is not difficult to control in the production of sheet and strip, but it is more difficult to control in the production of heavy duty aluminum foil.

As the thickness of the aluminum foil decreases, its trace conditions can affect it, such as temperature, oil film, and oil and gas concentration. Haomei aluminum foil production is equipped with Honeywell thickness gauge to ensure the control of outlet thickness.

The Popular Uses of Soft Aluminum Strips

The flexible aluminum strip is an aluminum deep-processed product formed by aluminum coil slitting. The raw materials of the aluminum strip are pure aluminum or aluminum alloy cast-rolled aluminum coils and hot-rolled aluminum coils.

Then they are rolled into aluminum coils of different thicknesses and widths by a cold rolling mill, and then longitudinally cut into different widths by a slitting machine according to the application. Currently, the commonly used ones should belong to the soft aluminum strips. It has two popular uses: aluminum spacer strip, aluminum nose wire, transformer aluminum strip.

Aluminum spacer strip

Compared with other materials, the aluminum strip for insulating glass is of strong corrosion resistance and high brightness. It is of uniform penetration, good straightness, no deformation, stable size, high strength, good toughness, which can be continuously bent into any angle of aluminum frame with bending equipment. More importantly, it can ensure the activity of molecular sieve and ensure excellent bonding with various glues.

Aluminum nose wire

The aluminum nose wire made of the bendable aluminum strips has a good shaping effect. It is in close contact with the corresponding parts of the wearer’s face and effectively fits the skin to block dust, smoke, flu viruses, etc.

It usually chooses 1060 or 3003 aluminum strip. They not only have high specification accuracy, good surface finish, regular winding,but also has good bending resistance, which can meet most technical requirements for the production of masks. Haomei bendable aluminum strips are fully in line with Eu standards and has passed the SGS, RoSH and MSDS test.

Aircraft Aluminum Grade 7068 vs 7075

High strength aluminum alloys have he advantages of low density, high strength, and good thermal processing performance. Different forms of aluminum alloys like aluminum sheet have broad application prospects in aerospace components. For example, high-strength aluminum alloy thick plates are used as the main load-bearing components, and the proportion of use accounts for 30% to 35% of the total aluminum consumption in the aircraft.

Aluminum grade 7075 has zinc as the main alloying element, and as a member of the 7000 series, its strength is very high, comparable to many types of steel. Although it has high strength, it has lower corrosion resistance than other common aluminum alloys and does not provide the same level of machinability or weldability.

7075 aluminum plate was successfully developed in 1943. It is the first practical application of 7xxx aluminum alloy for the manufacture of various structural parts, especially aerospace structural parts. It is the most widely used high-strength aluminum alloy today.

It is widely used to make aircraft front fuselage truss, passenger observation window frame forgings, middle fuselage sheet bending and truss, keel beam web, floor turning beam, middle and rear fuselage truss, phone shell,etc. Its common tempers are T6, T73, T76 and T77.

Car Aluminium 6016 vs 6061

The car body is the heaviest part in the car, accounting for about 30% of the car’s weight, so the aluminization of the car body plays a pivotal role, and the development of aluminum alloy materials for the car body is the key. 6xxx aluminum alloy is a main alloy for automobiles including Al6016 and 6061.

6016 aluminum alloy has the advantages of good fracture toughness, corrosion resistance, fatigue resistance, etc., and has a wide range of uses in aviation, aerospace, ships, transportation and construction. It is mainly used for the manufacture of doors, windows and invisible parts in the body structure.

Hemming is an important process in the assembly and pressing process of the inner and outer panels of automobile body panels. An important indicator to measure the performance of 6016 aluminum plate hemming is the bending limit. Generally speaking, the 6016 aluminum plate in O state is the softest and suitable for various bending shapes.

The main alloying elements of alum 6061 are Mg and Si, and form the Mg2Si phase, which is one of the most widely used aluminum alloys. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance.

Alum 6061 has good strength and toughness, excellent machinability, corrosion resistance and ideal anodizing effect after being treated and pre-stretched. After special treatment (T6), 6061 alloy achieves medium strength, and its strength is higher than that of 5 series alloys. It is often used to make fenders, car hood outer panel and card doors.

At present, the 6061 aluminum plate technology in China is relatively mature. Haomei Aluminum is one of the big aluminum sheet manufacturers. Our 6061 aluminum sheet thickness is of 0.2-500mm and a maximum width is of 2800mm. The common tempers are T6 and T651. Welcome to leave message below to inquire what you need.

5083 Alloy for LNG/Fuel/Air Storage Tank

No matter what kind of aluminum alloy it is, its mechanical properties increase with the decrease of temperature, so aluminum is a wonderful low-temperature structural material. 5083 alloy is a typical one, which is widely used for rocket low-temperature fuel (liquid hydrogen, liquid oxygen) storage tanks, liquefied natural gas (LNG) tanks, low-temperature chemical product containers, fuel tankers,etc.

Under the global background of green environmental protection, the tanker manufacturing industry has gradually chosen the lightweight development. 5083 aluminum alloy is mainly used instead of traditional steel.

5083 aluminum plate is an Al-Mg aluminum alloy. It has excellent corrosion resistance, good processing performance and welding performance. At the same time, the aluminum alloy itself is light in weight and high in specific strength. In addition to manufacture fuel and LNG tank, it is also used for making air storage tank.

The air storage tank is an important part of the braking system of heavy trucks, which is used for energy storage, filtration, voltage stabilization and cooling. There are many places where gas is used on trucks, ranging from the whistle to the brakes. If there is no air storage tank, the air volume pumped by the air compressor alone is not enough.

We all know that the air contains a lot of dust and water molecules, as well as the oil pumped in due to the failure of the air compressor. If it enters the air path of the vehicle, it will easily damage the vehicle parts over time, causing certain hidden dangers to driving safety.

The air pumped by the air compressor will stay in the air storage tank for a short time. Because the relative weight of water molecules, dust and oil in the air is heavier than that of air, it will fall to the lower part of the air storage cylinder. At this time, the air reservoir plays the role of filtering again.

The 5083 aluminum plate has good forming and processing performance. After being used in automobile air storage tanks, the air storage tank will not corrode and the service life will be extended. Haomei Aluminum has other main kinds of aluminum plate. Welcome to leave message below to inquire 5083 and 5754 aluminum sheet price.

The Main Series of Colored Aluminum Sheets

The colored aluminum sheet refers to aluminum sheet coated with one or several layers of polyester, fluorocarbon polyester and other organic coatings after surface processing, and then baked and cured. According to the different performance and application fields, color coated aluminum can be divided into two categories: functional type and ordinary type.

The downstream industries of the color coated aluminum coil are mainly construction, industry and food packaging industries such as construction needs of commercial office buildings, high-end hotels, urban rail transit and railway stations, containers, reefers, tankers,cans.

1060 aluminum alloy

1060 painted aluminum sheet belongs to the pure aluminum sheet. The density is 2.71. With good ductility, it has excellent forming processing characteristics, high corrosion resistance, long service life and low cost, but its strength and rigidity are low.

3003 coated aluminum sheet

It belongs to the aluminum-manganese alloy with a density of about 2.73. Due to the manganese alloy element (the content is between 1-1.5%), the material hardness and tensile properties are better than those of the 1 series. Since it has excellent anti-rust properties, 3003 aluminum is also known as “rust-proof aluminum”.

3004 color coated aluminum

In addition to manganese, the 3004 aluminum plate also adds magnesium, and the content is between 0.8-1.3%, so 3004 alloy has higher strength than 3003. It also has excellent formability, and good corrosion resistance, which is the most widely used color aluminum.

5052 colored aluminum sheet

The density of 5052 Al-Mg alloy is 2.68. The alloy composition is mainly magnesium, and its content is between 3-5%. The main features are low density, high tensile strength and high elongation. Its tensile strength is higher than that of the 3 series.

The aluminum coil stock colors is usually toned according to Ral or PANTONE color card. The paint is usually fluorocarbon or polyester paint. The popular colors are cappuccino, clay, coffee, espresso, silver metallic, tan, and white.

Haomei Aluminum dopts the international advanced roller coating process, which can ensure that there are no dust particles on the surface of the color-coated aluminum coil and no color difference. We only need you to provide the color card code to color for you, or you can send color samples to us.

Why Does Anodized Aluminum Panels Have Color Difference

The anodized aluminum panels are to place the aluminum plate in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and conduct electrolysis under specific conditions and the action of an applied current.

The anodizing aluminum sheet will have a thin layer of aluminum oxide on the surface with a thickness of 5-20 microns, and the hard anodized film can reach 60-200 microns. It not only has good durability, but also high aesthetics.

The surface of the anodized aluminum plate has a special very thin aluminum oxide layer, which increases the hardness and also improves the wear resistance. At the same time, the anodized aluminum plate has a very high melting point, which makes the anodized aluminum plate very durable. And the anodized aluminum plate not only has many excellent properties, but it is also relatively easy to color and has high aesthetics.

Why does the anodized aluminum plate have color difference?

1. When the material is oxidized, the treatment effect will be affected by factors such as the composition, content, concentration, temperature and treatment time of the potion, which will lead to different effects of the final product.

2. The color difference that already exists during the production of material pretreatment leads to increased difficulty in sample matching and color matching.

3. The metal element content and material texture of different batches of raw aluminum sheets cannot be consistent, and it is difficult to achieve exactly the same effect as the sample after multiple adjustments and sample evaluations during coloring processing.

It is unavoidable that there is a color difference in the anodizing aluminum sheet. However, each enterprise will regulate a color difference range, and the products within the range are normal products. As a big aluminium plate manufacturer, Haomei Aluminum has mature anodizing technology. Welcome to leave message to inquire what you need.

Why Is Aluminum Used for Aircraft Bodies

Why is aluminum used for aircraft bodies? Aircraft aluminum alloys have many excellent properties such as high toughness, corrosion resistance and fatigue resistance. Since the early 20th century, they have been widely used in the aviation field as the fuselage skin, beams, stringers,etc. According to the difference in the service performance and use of the aircraft, the amount and specifications of aluminum alloys on the aircraft are also quite different.

7xxx aluminum alloy is another commonly used alloy with a wide variety. It contains zinc and magnesium. The most common aluminum alloy with the best strength is 7075 aircraft aluminum. How about aluminum alloy 7075 properties?

7075 aluminum alloy is a cold-worked wrought alloy, one of the strongest commercially available alloys. It has normal corrosion resistance, good mechanical properties and anodic reaction. The finer grains result in better deep drilling performance, enhanced tool wear resistance and distinctive thread rolling.

7075 mainly contains zinc element, which is an aluminum-magnesium-zinc-copper alloy and a heat-treatable alloy. It is a super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress relieved and will not deform or warp after processing. All super-large and super-thick 7075 aluminum plates are ultrasonically detected, which can ensure no blisters and impurities. 7075 aluminum plate has high thermal conductivity, which can shorten the forming time and improve work efficiency.

After solution treatment, it has good plasticity, good heat treatment strengthening effect, good strength below 150 degrees, and particularly good low temperature strength, poor welding performance, and tendency to stress corrosion cracking.

7075 aluminum plate is generally added with a small amount of copper, chromium and other alloying element. Among this series, the 7075-T651 aluminum alloy is known as the best product in aluminum alloys. This alloy also has good mechanical properties and anodic reaction.
