7075 Aluminum Plate Sheet
7075 aluminum plate sheet is one of the highest strength aluminum alloys available. It has good machinability and an excellent strength to weight ratio, and it is a popular materials in applications where strength is extremely critical. 7075 aluminum plate sheet is often used for highly stressed parts, and has average corrosion resistance, improved resistance is normally obtained by cladding parts. Welding is generally not recommended. 7075 is a heat treatable grade of aluminum, and sometimes used in place of 2024.
7075 aluminum plate sheet have application throughout aircraft and aerospace structures where a combination of high strength with moderate toughness and corrosion resistance are required. Typical applications are alclad skin sheet, structural plate components up to 101.6mm in thickness and general aluminum aerospace applications.
Corrosion resistance
alloy 7075 aluminum plate sheet has been thoroughly evaluated for corrosion resistance of atmospheric weathering, stress-corrosion cracking and exfoliation in all currently available tempers. These values have been used as a standard for comparision in the development of more recent high strength aerospace alloys. Within the 7*** series of alloys, resistance to general corrosion attack, exfoliation improves significantly in the overage tempers(T7 type) compared with peak strength temper( T6). Generally, the T76 type temper is considered the exfoliation resistant temper, while the T73 type temper is considered the SCC resistant temper. It should be noted that T73 is as resistant to exfoliation as T76, but at lower strength levels. For applications where good surface appearance is required or in corrosive environments, alcald 7075 plate sheet are recommended.
Thermal treatment
Many heat treatments and heat treating practices are available to develop optimum strength, toughness and other desirable characteristics for proper application of alloy 7075 aluminum plate sheet products.
