7075 aluminum plate block bar

7075 aluminum plate block bar has high strength, high hardness, good corrosion resistance, mechanical properties and anode reaction
7075 aluminum plate block bar is a cold-treated forging alloy with high strength and hardness, far better than mild steel.
7075 aluminum plate block bar is one of the strongest commercial alloys, with ordinary corrosion resistance, good mechanical properties and anode reaction.
The finer grains make deep drilling performance better, tool wear resistance enhanced, thread rolling is more different, and the first choice for metal materials with lower density requirements and higher hardness requirements.

The purpose of 7075 aluminum plate block bar:
7075 aluminum plate block bar are used to manufacture aircraft structures and other high-stress structural parts that require high strength and strong corrosion resistance, such as aircraft upper and lower wing panels, stringers, bulkheads, etc. After solution treatment, the plasticity is good, and the heat treatment strengthening effect is particularly good. It has high strength below 150℃, and has particularly good low temperature strength, poor welding performance, and stress corrosion cracking tendency. Two-stage aging can improve the SCC resistance.
