Principal Design Features		Brazing sheet and strip

Applications		Commonly used in the manufacture of pistons.

Machinability		Machinability of AL 4032 is fair to good. Use of lubricating oils during machining is recommended.

Forming		This is basically a forging alloy and forming is done by hot die forging.

Welding		The alloy is weldable and use of inert-gas arc welding is the preferred method . Gas welding should be avoided.

Heat Treatment		Solution heat treatment is done at 950 F for 1 to 12 hours, depending upon section thickness. Cold water quench.

Forging		This is a forging alloy and hot die forging is done at temperatures in the range of 950 F to 700 F.

Hot Working		The same comments as for "Forging" apply to hot working. That is hot work in the range of 950 F to 700 F.

Cold Working		No data. This alloy is typically hot forged, not cold worked.

Annealing		Annealing may be done at 775 F for adequate time for thorough heating, followed by controlled cooling at rate of 50 F per hour to 400 F then air cool.

Aging		The alloy may be aged (T6 temper) by first solution heating at 950 F and cold water quenching, followed by a 340 F heating for 10 hours and air cooling.

Tempering		Not applicable

Hardening		See "Aging".

Other Physical Props		Electrical conductivity 33% of copper.

Other Mechanical Props		Shear strength for the T6 condition is 38 ksi at room temperature.
