7475 Aluminum Plate

What is 7475 Aluminum Plate?

The 7457 Aluminum Plate is a high-strength alloy in the 7000 series, engineered for applications requiring superior mechanical properties and good corrosion resistance. It belongs to the aluminum–zinc–magnesium–copper system, offering an excellent combination of strength, toughness, and stress-corrosion cracking resistance. Although not a widely standardized alloy, 7457 aluminum plate is comparable in performance to 7050 or 7475 grades, often used in aerospace, defense, and precision engineering fields. The material can be supplied in tempers such as T6, T651, or T7451, with typical thicknesses ranging from 6 mm to 200 mm. Common surface finishes include mill finish, anodized, and Alclad coating. It conforms to typical high-strength aluminum standards such as ASTM B209 and AMS specifications for aerospace-grade plates.
