Thickly Walled 7075 T73 Seamless Aluminum Tubing High Strength For Aerospace Application
7075-T73 Seamless Aluminum Tubing
has excellent stress corrosion resistance and high strength properties and is used in the manufacture of aircraft and high performance industries.
7075 alloys providing superior strength and elongation under stress.
The process starts with a hot billet being pierced by a mandrel. A ram is pushed against a die and forties out the aluminum. With a fores in excess of 4,000 tonnes the aluminum is extruded through the die and over the mandrel.
