Aluminum Sheet Coil Factories

There are aluminum sheet coil factories in China, Chinese manufacturer are well known on the world market for good price and fast product. Aluminum coil manufacturer produce 1060, 3003, 5052 and 6061 aluminum sheet roll with prime quality.

What properties should be considered when select aluminum sheet coil factories?

1, Hardness

Many customers are very concerned when purchasing aluminum sheet coil, and the preferred hardness is directly related to the chemical composition of the alloy. Secondly, the state is different, the impact is relatively large. Different countries also have a great influence. In terms of the highest attainable hardness, 7000 series, 2000 series, 4000 series, 6000 series, 5000 series, 3000 series and 1000 series are successively lower.

2, Corrosion resistance

Corrosion resistance includes chemical corrosion resistance and stress corrosion resistance. Generally speaking, series 1000 pure aluminum coil has the best corrosion resistance, series 5000 performs well, series 30000 and 6000 are the next, and series 2000 and 7000 are poor. The selection criteria for corrosion resistance should be based on the application site. When high-strength alloys are used in corrosive environments, various composite materials are required for anti-corrosion.

3, Machinability:

Machinability, insert molding performance and cutting performance. Since the formability is related to the state, after selecting the aluminum coil grade, the strength range of each state should be considered. Generally, high-strength materials are not easy to form. Conversely, aluminum materials should be bent, drawn and deep drawn, with annealed materials having the best formability and heat-treated materials having the worst formability. The machinability of aluminum plate is poor, and molds and mechanical parts require better machinability. On the contrary, the machinability of aluminum sheet is an important consideration factor for molds and machine parts products.

4, Weldability:

Most aluminum sheets have no problem with weldability, especially some 5000 series aluminum coil are specially designed for welding. On the other hand, some 2000 series and 7000 series aluminum coil are difficult to weld.

5, Decorative

When aluminum is used for decoration or some special places, it needs to be anodized and coated on its surface to obtain the corresponding color and surface texture. At this time, its decorative properties should be mainly considered. Generally speaking, materials with good corrosion resistance have excellent anode treatment performance, surface treatment performance and coating performance.
