Aluminum / EXT 7075 ALUM T73511

Grade 7075 Extruded (EX) / T-73511 Temper Aluminum is solution heat treated and stabilized by overaging, then stress relieved by stretching. This product is artificially overaged after solution heat treatment to provide maximum strength. This product also receives minor straightening in order to comply with standard tolerances. Aluminum alloy 7075 is well-known for its excellent strength-to-weight ratio, making it an ideal material for applications where weight is a critical factor. 7000 series are the hardest and strongest commercial grades of aluminum. Grade 7075 is the most common of the 7000 series grades. This alloy is precipitation hardened to very high strength levels making it ideal for the production of airframe structures and other highly stressed components. (UNS A97075)
