7475 Aluminium Plates
Champak industries supplier of 7475 Aluminium Plates/ 7475 Plate is available in
T651, T7651 and T7351 tempers. Alloy 7475 aluminum plates are a controlled toughness alloy whose
values are 40 percent greater than alloy 7075 in the same tempers. This alloy's corrosion resistance
and fatigue behavior are also equal to, or better than, many of the other high strength aerospace
alloys, and is for those applications that require a combination of high strength, superior fracture
toughness and resistance to fatigue crack propagation.
