aluminum and other metal materials aluminum Alloy, compared with some of the following characteristics:
1, low density
aluminum and aluminum Alloy densities approaching 2.7g /, about 1/3 of iron or copper.
2, high strength
high strength aluminum and aluminum Alloy's. After a certain degree of cold working can enhance the matrix strength, some grades of aluminum Alloy can also be strengthened by heat treatment.
3, good thermal conductivity
electrically and thermally conductive properties of aluminum second only to silver, copper and gold.
4, good corrosion resistance
Easy natural production of surface aluminum layer of dense solid AL2O3 protective film substrate can be well protected against corrosion. By artificial anodizing and coloring, get a good casting performance cast aluminum Alloy or processing of plastic deformation of aluminum Alloy.
5, easy processing of Alloy after adding certain elements, get a good casting properties of cast aluminum Alloy or processing of plastic deformation of aluminum Alloy. Due to the excellent Physical properties, aluminum has been widely used in various sectors of the national economy and national defense industry.
7075 Aluminium sheet performance:
Alloy 7075 is the main element of zinc, the intensity is very strong, with good mechanical properties and the anode reaction. Mainly for the manufacture of aircraft structures and Other high strength, high stress corrosion resistance of structural components, such as on an airplane, lower wing facing the wall panels, beams and so on. Good plasticity after solution treatment, heat treatment to strengthen good effect, at 150 degrees below have good strength, and there is poor particularly good low temperature strength, weldability, stress corrosion cracking tendency. Also widely used in mold processing, machinery and equipment, tooling and fixtures.
