GNEE 7075 Aluminum Plate Overview
GNEE is a professional distributor and supplier of 7075 aluminum plate, one of the highest-strength aluminum alloys available. Known for its excellent mechanical performance and reliable corrosion resistance, 7075 aluminum plate is widely used in demanding, high-stress applications.
7075 aluminum uses zinc as its primary alloying element, with zinc content ranging from approximately 1% to 8%, enabling the alloy to achieve strength levels comparable to certain steels through precipitation hardening.
In the T651 temper, 7075 aluminum plate undergoes solution heat treatment followed by controlled stretching to relieve internal stress. It is then artificially aged, allowing alloying elements to precipitate and deliver maximum usable strength immediately.
