7068 Aluminum Alloy Pipe Extruded Seamless Aluminum Tube
7068 Aluminum Alloy Pipe Extruded Seamless Aluminum Tube
7068 alloy provides the highest mechanical strength of all aluminum alloys and matches 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 component/equipment designers. Developed in the mid-1990s, 7068 alloys were designed as a higher strength alternative to 7075 for ordnance applications.
