Product Overview
Aviation ultra-hard aluminum alloy, high strength, excellent wear resistance; 7050 is a high-strength heat-treatable alloy, known for its high strength, good wear resistance, and resistance to spalling corrosion and stress corrosion cracking. Commonly used in aircraft structural components for medium and thick plate extrusions, free forging, and die forging.
Product Application
7050 is primarily used for manufacturing aircraft structures and high-stress components with high strength and corrosion resistance, such as upper and lower wing surface panels, struts, etc. It exhibits good plasticity after solution heat treatment and excellent heat treatment strengthening. It maintains good strength below 150 degrees Celsius and exceptional low-temperature strength. It has poor welding properties and a tendency to stress corrosion cracking. It is also widely used in mold making, machinery and equipment, fixtures, aerospace and aviation industries, blow molding (bottle) molds, ultrasonic welding molds, golf ball heads, shoe molds, paper-plastic molds, foam molding molds, dewaxing molds, machinery and equipment, and for producing high-end aluminum alloy bicycle frames.
