1, Aluminum hardness:
Many customers are very concerned about the aluminium profile of aluminium profile suppliers, the preferred aluminum alloy hardness has a direct relationship with the chemical composition. Second, the different states also have a greater impact, from the highest hardness can be achieved, 7 series, 2 series, 4 series, 6 series, 5 series, 3 series, 1 series, followed by lower.
2, Aluminum processing:
Aluminum processing properties include: formability and cutting performance. Because formability and the state, the choice of aluminum alloy grades, the need to consider the intensity range of various states, usually high strength aluminum is not easy to shape. Followed by the aluminum bending, drawing, deep drawing and other forming, finished annealed state of the best material formability, on the contrary, the state of the heat treatment of the worst formability of the material.
3, Aluminum weldability:
Most aluminum alloy profiles are weldable, especially for some 5-series aluminum profiles, which are designed for welding. Relatively speaking, some 2-and 7-series aluminum profiles are harder to weld.
In addition, the strength of the product design must be considered an important factor, followed by aluminum components as a component, should be based on the pressure to choose the appropriate aluminum profiles. The lowest strength of pure aluminum, and 2 and 7 series heat-treated aluminum alloy highest strength, hardness and strength have a certain correlation. Corrosion resistance should also pay attention to the next.
