7075 t6 aluminum plate supplied by Haomei is a cold-treated forging alloy with high strength, far superior to mild steel. 7075 aluminum is one of the commercial strength alloys, with general corrosion resistance, good mechanical properties and anode reaction. In general, the chemical corrosion resistance of 7075 aluminum alloy is higher than that of duralumin alloy, but lower than that of Al Mn, Al Mg, Al Mg Si alloy. The corrosion resistance of superhard aluminum plate with aluminum cladding is greatly improved. For extrusion materials and forgings without aluminum coating, 7075 aluminum plate can be protected by anodizing or spraying.
The stress corrosion resistance of superhard aluminum alloy is poor under the condition of quenching and natural aging, but it is increased under the condition of quenching and artificial aging. The research shows that the stress corrosion sensitivity of 7075 aluminum plate and aluminum bar can be reduced by the step aging process. The hardness of 7075-T6 aluminum plate is about 150HB. The main alloy element of 7075 aluminum is zinc, which has high strength, good mechanical properties and anode reaction. It is mainly used to manufacture aircraft structures and other high stress structural parts with high strength and strong corrosion resistance, such as upper and lower wing panels, purlins, etc.
After solution treatment, it has good plasticity, good heat treatment strengthening effect, good strength below 150 ℃, especially good low temperature strength, poor welding performance and stress corrosion cracking tendency. 7075 t6 aluminum plate is also widely used in mold processing, mechanical equipment, tooling and fixture, etc
