The 7 series aluminum sheets, part of the ultra-hard aluminum alloy series, primarily consist of zinc, magnesium, and copper as the main alloying elements. Representative grades include 7050 and 7075. These are high-strength wrought aluminum alloy sheets known for their excellent heat treatment properties. After solid solution treatment, they exhibit good plasticity, along with exceptional mechanical strength, wear resistance, and fatigue resistance. However, their drawback lies in poor weldability and susceptibility to stress corrosion cracking, necessitating cladding or other protective treatments. They find extensive applications in aerospace materials and are also used in various mechanical, mold-making, and machining industries.
7050 Aluminum Sheet
7050 aluminum sheet's main alloying element is zinc. By adding magnesium to alloys containing 3%-75% zinc, significant strengthening effects can be achieved, primarily through the formation of MgZn2. This results in superior heat treatment properties compared to binary aluminum-zinc alloys. 7050 aluminum sheets are employed in the manufacture of aircraft structures and other high-stress components requiring high strength and corrosion resistance.
7050 aluminum sheets are commonly used in aerospace, mold machining, mechanical equipment, and tooling fixtures, especially in the construction of aircraft structures and other high-stress components demanding high strength and corrosion resistance.
7075 Aluminum Sheet
7075 aluminum sheet belongs to the ultra-hard aluminum category and is a cold-worked forging alloy known for its high strength and hardness, surpassing that of mild steel.
7075 aluminum sheets find applications in aerospace and aviation industries, blow molding (bottle) molds, ultrasonic plastic welding molds, golf club heads, shoe molds, paper plastic molds, foam forming molds, wax pattern molds, templates, fixtures, mechanical equipment, mold processing, and the production of high-end aluminum alloy bicycle frames, among other fields.
