Prodsuct Introdsuction
7050 aluminum rods is the main alloy elements zinc, to add magnesium alloys containing 3% 75% zinc, can form the strengthening effect is remarkable MgZn2, make zinc-aluminum alloy heat treatment effect than the binary alloy. Improve zinc magnesium content in the alloy, tensile have to be to further improve the hardness, but its resistance to stress corrosion and spalling corrosion with the decrease of the ability. After heat treatment can achieve very high strength characteristics. These materials are generally to join to discuss copper chromium alloy, etc. In the department at 7075-7651 aluminum alloy after taste, is praised as the most excellent prodsucts in aluminum alloy, high intensity, far more than mild steel. The alloys have good mechanical properties and anode reaction. It is mainly used in aerospace, mold processing, mechanical equipment. Fixture, especially used in aviation manufacturing structure and other high-stress structure with high strength and corrosion resistance

Prodsuct Feature and Application
7050 aluminum bars is a high-strength heat-treatable alloy with extremely high strength and resistance to peeling corrosion and stress corrosion fracture. Commonly used in aviation structural parts for medium and thick sheet extrusion parts, free forging parts and die forging parts. The requirements for making this kind of part are as follows: the ability to resist spalling corrosion and stress corrosion cracking, fracture toughness, and fatigue resistance.
