7150-T6151 Aluminium Alloy Plate
Description
Alloy 7150-T6151 is the highest strength aluminum plate alloy/temper currently available for commercial aircraft applications. A controlled toughness alloy with guaranteed levels of fracture toughness, this alloy is a potential replacement for 7075-T651 since it provides 6 to 10 ksi (41.4 to 68.9 MPa) higher strength levels. Alloy 7150 is a second generation version of alloy 7050, developed specifically for peak strength properties in 0.75 to 1.5 inch (19.1 to 38.1mm) thick plate.
Alloy 7150-T6151 is recommended for applications which can take advantage of its high tensile/ compressive properties where exfoliation and stress corrosion cracking (SCC) requirements are similar to 7075-T651.
Applications
Alloy 7150 is currently being used for upper wing skins on large commercial aircraft where high compressive yield strength is the major requirement.
