Product Introduction An Aluminium Alloy with the Strength of Steel 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 alloys) and good ductility with corrosion resistance similar to 7075 and other features beneficial to high-performance componentequipment designers. Developed in the mid-1990s, 7068 alloys was designed as a higher strength alternative to 7075 for ordnance applications.
