Key Characteristics of 7075 Aluminum<\/h2>\n

Hoge sterkte<\/h3>\n

7075 is one of the strongest commercial aluminum alloys, with T6\/T651 yield strength around 505 MPa.<\/p>\n

Corrosion Resistance & Stress Corrosion<\/h3>\n

Bare 7075 has moderate general corrosion resistance. The T73\/T7351 tempers improve resistance to stress-corrosion cracking, especially in thicker sections.<\/p>\n

Machinability & Weldability<\/h3>\n

Machinability is excellent in the T6 condition. Weldability is poor \u2014 fusion welding is generally not recommended; mechanical fastening or adhesive bonding is preferred.<\/p>\n
