Applications

Commonly employed in electronic equipment such as radios, laser systems and thermostats.

Machinability

This alloy can be machined employing most common methods. It is known to produce "gummy" chips and is best machined at slow speeds with positive and constant feeds.

Forming

The alloy is readily formed using most common practices and should not present any unusual problems. For maximum properties, material should be fully annealed after any forming operations.

Welding

All common joining techniques can be successfully employed here. When a filler metal is required, it is suggested to use a similar composition alloy, available from the manufacturer.

Forging

Heat to 2150 F(1180 C) rapidly and cool rapidly following working. Do not soak at temperature.

Cold Working

This alloy can be cold upset and swaged successfully.

Annealing

Hold at 1450 F(790 C) 30 minutes for every inch of thickness, followed by air cooling. To obtain maximum dimensional stability, soak at 1500 F(815 C) and water quench. Reheat to
