7068 Commercial Aluminium Alloy7068 Aluminium Alloy

An Aluminium Alloy with the Strength of Steel

7068 alloy provides the highest mechanical strength of all aluminium alloys and matching that of certain steels.

This outstanding alloy combines a yield strength of up to 700 MPa (up to over 30% greater than that of 7075 alloy) and good ductility with corrosion resistance similar to 7075 and other features beneficial to high performance component/equipment designers. Developed in the mid 1990’s, 7068 alloy was designed as a higher strength alternative to 7075 for ordnance applications.

The highly attractive overall combination of mechanical properties (retained at elevated temperatures better than 7075) and other important characteristics of 7068 have resulted in the widespread specification of the alloy to markedly reduce the weight/cross section or significantly increase the strength of critical components in diverse market sectors.

An Aluminium Zinc Alloy

7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment).

7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS. The standard supply temper condition is T6511. For applications requiring greater resistance to stress corrosion cracking the T76511 condition is available to order.
