7075 Aluminum Sheet Plate
7075 aluminum alloy is a high-strength, heat-treatable alloy belonging to the 7000 series (Al-Zn-Mg-Cu). Often referred to as "aircraft-grade" aluminum, it is one of the strongest aluminum alloys commercially available. Zinc is the primary alloying element, providing exceptional mechanical properties and high hardness. Due to its superior strength-to-weight ratio, it is the standard material for highly stressed structural parts, particularly in aviation and aerospace applications where performance and reliability are critical.

Overview
7075 aluminum sheet plate is an Al-Zn-Mg-Cu series ultra-high-strength heat-treatable alloy, widely known as aerospace-grade super-hard aluminum. It features extremely high tensile strength, hardness, and excellent mechanical properties, with chromium added to improve stress corrosion cracking resistance and zinc providing strength close to steel. It is widely used in high-end equipment, aerospace, military, mold, and automotive fields that demand ultra-high strength and lightweight performance.
