T7451 T7651 7050 Extruded Solid Aluminum Bar Building Materials
7050 Solid Aluminum Bar Metal Building Materials Aluminum Bar
7050 Aluminum Bar Characteristics:
7050 aluminum bar is the aluminum of the aerospace grade which has stress corrosion resistance, high strength as well as toughness. This alloy heat treatable and possess high mechanical properties as well as high fracture toughness. This alloy is available in the two tempers mainly T7451 as well as T7651. It has good electrical conductivity. This alloy cannot be used for welding purpose as it weakens alloy.

7050 Aluminum Bar Features:
Alloy 7050 aluminum bar remain the baseline standard with a good balance of properties required for aerospace applications.
7050 aluminum bar is among the highest strength alloys available and is used in highly stressed parts.
Corrosion resistance and machinability are rated as fair, though the addition of chromium provides good stress-corrosion cracking resistance in 7050 aluminum bar products. As with alloy 2024, alloy 7050 is available in the bare form or in the cladding ("Alclad") to offer even further protection from corrosion.
7050 Aluminum Bar Applications:
7050 is mainly used for manufacturing aircraft structures and other high-stress structural parts with high strength and corrosion resistance. Such as on the plane, under the wing panel, truss, etc. After solid solution treatment, the plasticity is good, the heat treatment strengthening effect is good, has the good strength below 150 degrees, and has the particularly good low temperature strength, Poor welding performance, stress corrosion cracking tendency.
Widely used in aerospace industry,mechanical equipment, fixtures, mold processing, blow molding (bottle) mold, ultrasonic plastic welding mold, golf head, paper mold, shoe mold, wax mold, foam molding mold, mechanical equipment, used in the production of high-end aluminum bicycle frame.
