ASTM Aluminum Plate 7075 T651 Aluminum Sheet

 7075 T651 Aluminum Sheet is available in bare and alclad sheet and plate product forms in the annealed state as well as several tempers of the T6, T73 and T76 types.

Alloy 7075 has been thoroughly evaluated for corrosion resistance of atmospheric weathering, stress-corrosion cracking and exfoliation in all currently available tempers. These values have been used as a standard for comparison in the development of more recent high strength aerospace alloys.

 7075 T651 Aluminum Sheet is a very poor choice for welding. Resistance welding is the only preferred method of joining 7075. Gas welding should be avoided and the use of arc welding may result in degradation of corrosion resistance.

 7075 T651 Aluminum Sheet has a lower level of corrosion resistance and has no weldability, i.e. it is not weldable. This particular kind of alloy is known for its level of fatigue strength, however, it is only average when it comes to machinability.
