Aluminum 7075 Material Properties

7075 aluminum sheet is a commonly used grade in the 7xxx aluminum alloys. Zinc is its main alloying element. The addition of magnesium to the alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, so that the heat treatment effect of 7075 aluminum is far better than that of the aluminum-zinc binary alloy.

Aluminum plate 7075 is used to manufacture a variety of structural parts, especially aerospace structural parts. It is the most widely used high-strength aluminum alloy today, ranging from the front fuselage truss of the C919 large aircraft to the mobile phone casing. What are aluminum 7075 material properties?

It is available in various heat treatment tempers: T6, T73, T76, T77. Through a large number of experimental data and theoretical analysis, on the basis of 7075-T6, the aging heat treatment process was used to successfully develop 7075-T73, which is resistant to stress corrosion. Although this material sacrifices part of its static strength, its corrosion resistance has been significantly improved.

Later, 7075-T76 was further developed, which not only obtained stronger corrosion resistance, but also sacrificed a lower static strength than 7075-T73, which improved the comprehensive properties of aluminum alloy materials and became the best corrosion-resistant aluminum alloy.

7075 alloy can be resistance welded, and the long-term working temperature of the workpiece is less than or equal to 125℃. For incomplete annealing of materials or workpieces, the specification is 290°C~320°C, and after holding for 2h~4h, it is air cooled. Complete annealing specification is (390~430)℃/(0.5~1.5)h and it should be cooled down to ≤200℃ with a cooling rate not greater than 30℃/h.

The solution treatment temperature of 7075 alloy sheet is 460℃~490℃, and the treatment temperature of aluminum sheet should be close to the lower limit, and the number of repeated treatments should not be more than 2 times, so as to prevent alloy elements from diffusing through the aluminum clad layer and reducing the corrosion resistance of the material.

5182 5754 Aluminium Alloys Used in Automotive Applications

In the production process of aluminum alloy body panels, most of the car panels choose 5xxx or 6xxx aluminum alloys. At the same time, in the welding operation of aluminum alloy body panels, you can choose to apply 5 series special welding wire to improve the effect of the aluminum alloy production process.

The automotive aluminum sheets have lower plasticity than steel plates, making it difficult to form parts with complex shapes. In particular, high-strength aluminum alloys are prone to problems such as cracking and springback. In order to solve the problem of aluminum alloy forming, the industry developed a hot forming process. Aluminum alloy plates suitable for hot forming include 5754, 5083, 6111, 7075 and 5182 aluminum sheet.

The yield strength of 5XXX series aluminum alloy automotive sheets is an important indicator that affects its forming springback, and can be controlled by the solid solution content of Mg and the grain size. During the stamping and forming process of 5XXX series aluminum alloy sheets, forming lines are prone to appear on the surface and must be strictly controlled. In order to further improve the lightweight effect, Cu or Zn elements can be added to the 5XXX series aluminum alloy to achieve precipitation strengthening through baking paint.

For the all-aluminum body, the outer automobile body panels use 6000 series alloy, the inner panels use 5052-0 alloy, and most of the frame uses 5182-0 alloy. Since the side door frames have high requirements for strength and stiffness, they use 6N01 alloy as the basis and appropriately adjust the content of Mg and Si.

5182 alloy is a typical aluminum-magnesium alloy with good processing and formability, corrosion resistance and good weldability. Due to the processing and forming properties, plasticity and relatively good elongation of 5182, it is widely used in automobile body panels.

5754 aluminum alloy is used in the manufacturing of door linings. It has the advantages of high strength, good plasticity, high specific strength, good welding performance, strong temperature resistance, good corrosion resistance, and high fatigue resistance. EN AW 5754 h11 is its common temper.

Creating a new ABS aluminum alloy system currently seems almost impossible. We can only optimize the composition of the alloy based on the existing 6xxx series alloys and create an ABS outer plate with better overall performance than the 6016 alloy. Based on the existing 5xxx series alloys, we will create an inner plate ABS alloy with better overall performance than 5754. At the same time, the new alloy should have a better cost performance.

5083 5383 Aluminum Sheet for Boat Building

Since 1891, aluminum alloys have been used in the shipbuilding industry for nearly a hundred years. With the rapid development of the shipbuilding industry at home and abroad, the lightweight of ships is increasingly valued. Due to its low density, high strength and strong corrosion resistance, aluminum is very suitable for the harsh environment of the ocean.

In order to continuously improve the comprehensive performance of 5000 series marine aluminum alloys, many tempers like H116, H321, H323, etc. through deformation heat treatment processes on the basis of traditional alloys such as 5456, 5083, and 5086 have been developed. On the other hand, new 5-series aluminum alloys are constantly being developed by optimizing alloy compositions, such as 5383 aluminum registered in 1995 and 5059 aluminum alloy registered in 1999.

5083 aluminum plate belongs to the Al-Mg series aluminum alloy. It has the highest tensile strength and good weldability among all non-heat-treated strengthened aluminum alloys. It is also extremely resistant to seawater corrosion and is recognized as the best marine aluminum alloy for boat building.

The activation ring of 5083 aluminum alloy in seawater is small and it is easy to return to the passive state. At the same time, the breakdown potential and protection potential are higher than the self-corrosion potential in the stable state, which reflects its good corrosion resistance in seawater. Pitting corrosion is also the main corrosion form of 5083 aluminum alloy.

In the ship design industry, 5083 H116/H321/H112 tempers are often used. 5083H111 and 5083H112 themselves belong to the same 5083 aluminum alloy. They are essentially the same and have no difference in chemical composition. 5083 h34 is not often used for shipbuilding.

5383 aluminum alloy has increased corrosion resistance and 10% increase in impact strength. At the same time, its processing characteristics such as forming, folding, shearing, and welding are almost the same as those of 5083. This makes 5383 alloy more useful in building larger and faster ships.

As the annealing temperature increases and the cold rolling processing rate decreases, the spalling corrosion resistance of cold-rolled 5383 aluminum alloy increases. 5383 aluminum alloy has high strength and good corrosion resistance after cold rolling with a processing rate of 30%~45% and annealing at 225℃~250℃ and holding for 3 hours.

What Is Aluminum Trim Strip

The aluminum trim strip is usually a kind of color coated aluminum strip, adopting a two-coating and two-baking process, that is, after the surface pretreatment of the aluminum coil, the primer (primary coating) and topcoat (finishing coating) are applied and baked twice. It can carry out back coating and embossing or printing processing as needed.

One of its main application is ceiling. In suspended ceilings made of mineral fiber panels, colored aluminum strip can enhance the decorative appearance of the ceiling support structure. This narrow, thin coated aluminum strip is often used to cover the surface of T-rails. The aluminum strip ceilings are being manufactured in different widths and at any desired length.

According to the type of coating, pre-coated aluminum coils can be divided into two categories: PVDF coated aluminum coil and PE coated aluminum coils. Fluorocarbon pre-coated aluminum coils are aluminum products with excellent weather resistance, UV resistance, chemical corrosion resistance and self-cleaning properties.

Polyester pre-coated aluminum coil refers to coating the surface of the aluminum coil with coating containing polyester resin to form an aluminum product with good adhesion, rich colors and environmental protection performance.

It consists of a three-layer structure, namely aluminum alloy substrate, aluminum oxide film and coating. The aluminum alloy substrate is the supporting layer of colored aluminum, which provides the strength and toughness of colored aluminum. Generally, 3000 series or 5000 series aluminum alloys are used. The coating is a decorative layer of colored aluminum that is cured at high temperatures and can appear in various colors and patterns.

The roller coating method refers to applying the organic coating evenly on the aluminum coil through a roller coater after pretreatment on the surface of the aluminum coil, and then through drying, solidification, cooling and other processes to form a color coating with a certain thickness and performance. The roller coating method can achieve single-sided or double-sided color coating, or multi-layer or multi-color color coating to meet different needs and effects.

The color coated aluminum strips for sale are processed from aluminum coils through slitting equipment, so the processing thickness and tolerance of the aluminum strips are closely related to the slitting equipment. Our aluminum flexible strip slitting equipment comes from Germany, which can effectively control the width tolerance. The tolerance can be controlled within 0.05mm. Currently, it can slit aluminum strips with a thickness of 0.15-3.0mm, ensuring no scratches and accurate width tolerance control.

The Coating Durability Testing of 1100 Prepainted Aluminum Coil

1100 color coated aluminum coil can be used for decoration and protection of building exterior walls, roofs, walls, windows, etc. It can improve the aesthetics and durability of buildings, and has very good wind and fire resistance.

At the same time, there are many types of 1100 prepainted aluminum coils, which can be customized and processed according to design requirements, making them very flexible and diverse. On the other hand, 1100 aluminum coil stock can also be used in interior decoration and furniture manufacturing.

The durability of the coating film is the service life of the coating film. This is the most important quality index of coatings and coating films. It is a comprehensive expression of various functions and an expression of the true practical value of coatings.

The durability of the coating film is the durability of the coating itself to the atmosphere, so the weather resistance test of the coating is very necessary. There are two main methods for testing the durability of coatings, namely the atmospheric aging test and the artificial accelerated aging test.

During the use of coatings, they are affected by various factors, which cause irreversible changes in the chemical and mechanical properties of the coating film, eventually leading to damage to the coating. This change phenomenon is called the aging of the coating film.

The atmospheric aging test of coatings is to study the aging damage effects of various atmospheric factors, such as sunlight, wind, snow, rain, dew, temperature, humidity, oxygen, chemical gases, etc., on the coating in various climate areas. The appearance of the test panel is inspected to determine its durability.

It is also quite complex and difficult to conduct experiments and tests based on various actual conditions, and it is also difficult to obtain accurate results. Therefore, the testing methods for the durability performance of coating films are also constantly improving. Artificially accelerated aging experiments is the one.

The artificial accelerated aging experiment is based on the atmospheric aging experiment to find out the relationship between climate factors and coating film damage, so as to artificially create a simulated climate environment in the laboratory and conduct coating aging experiments in various types of climates.

Light source is a very important factor in the aging of coating films, and it is directly related to the type of light and the amount of irradiation. In particular, ultraviolet rays are more damaging to the coating film. The temperature, humidity and oxygen content in the atmosphere all play an important role in the aging of the coating film.

The artificial aging test is to use certain equipment, namely an artificial aging machine, to control factors such as changes in light source type and intensity, as well as changes in temperature, humidity, and oxidation content of various types of weather. Monitor the aging degree and changes of various coating films under artificial climate environmental conditions, and then measure the aging resistance of the corresponding paint film, that is, aging resistance.
