Aluminum Sheets Aluminum Stock 90% Aluminum Component Al Plate 7075 Aircraft Grade Aluminum
7075 aluminum is composed of 90.0% Al, 5.6% Zn, 2.5%Mg, 0.23%Cr, and 1.6% Cu, though these numbers nominally fluctuate depending upon manufacturing factors. Its density is 2.81 g/cm3 (0.102 lb/in³), which is relatively light for a metal. 7075 aluminum alloy is one of the strongest aluminum alloys available, making it valuable in high-stress situations. The copper content of 7075 aluminum increases its susceptibility to corrosion, but this sacrifice is necessary to make such a strong-yet-workable material.
Applications of 7075 Aluminum
Type 7075 aluminum is one the strongest aluminum alloys. Its high yield strength (>500 MPa) and its low density make the material a fit for applications such as aircraft parts or parts subject to heavy wear. While it is less corrosion resistant than other alloys (such as 5052 aluminum alloy, which is exceptionally resistant to corrosion), its strength more than justifies the downsides. Some major applications of 7075 aluminum alloy include:
