Zinc is the main alloy element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with significant strengthening effect, making the heat treatment effect of this alloy far better than that of aluminum-zinc binary alloy. By increasing the zinc and magnesium content in the alloy, the tensile strength will be further improved, but its ability to resist stress corrosion and spalling corrosion will be reduced.
1. High strength heat treatable alloy.
2. Good mechanical properties.
3. Good ease of use.
4. Easy to process and good wear resistance.
5. Good corrosion resistance and oxidation resistance.
6. The anodizing effect is good.
Tensile strength and heat treatment of 7075 aluminum plate
After heat treatment, very high strength properties can be obtained. 7075 materials are generally alloys with a small amount of copper, chromium, etc., among which a7075 aluminum alloy is the most superior product. It is considered the best product among aluminum alloys, with high strength, far superior to any mild steel.
