ALUMINIUM
Aluminium 7075
Aluminium 7075
7075 aluminium alloy is a very high strength aerospace aluminium and is widely used in applications where the strength of the material is critical and the need for good corrosion resistance is not essential. Offering superior stress corrosion resistance, 7075 provides very high yield and tensile strengths, especially as determined by the temper selected.
Usage Areas :
- Aircraft structures
- Gears and shafts
- Automotive sector
- Parts requiring high strength in the defence industry
