Product Description

7475 Aluminum Plate

7475 aluminum plate

Alloy 7475 aluminum plate 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.

Applications of 7475 Aluminum Plate:

•Wings spars
•Fuselage bulkheads
