Aluminium extrusion square tube 7075 T6

Aluminium extrusion square tube 7075 T6 offers the highest strength of the common screw machine alloys. The superior stress corrosion resistance of the T173 and T7351 tempers makes alloy 7075 a logical replacement for 2024, 2014 and 2017 in many of the most critical applications. The T6 and T651 tempers have fair machinability. Aluminium extrusion square tube 7075 T6 is heavily utilized by the aircraft and ordnance industries because of its superior strength.

7075 in the T6 condition has a machinability rating of 80% when compared to 2011 at 100%. 7075 is can be formed in the annealed condition. 7075 may be forged in the temperature range of 700° to 900°F. It should be solution heat treated following forging. Aluminium Square Tube 7075 is a very poor choice for welding. Resistance welding is the only preferred method of joining 7075. Gas welding should be avoided and the use of arc welding may result in degradation of corrosion

Aluminium extrusion square tube 7075 T6 Typical application :
