Principal Design Features		Nickel 205 is one of the family of essentially pure nickel materials. In this instance the alloy contains small additions of aluminum and titanium for a good combination of mechanical and electrical properties.

Applications		Used for terminals, mechanical supports, and other related components in vacuum tubes for electrical devices.

Machinability		Machinable by standard means. High-speed tool steels with highly positive rake angles are preferred for cutting.

Forming		The alloy is very ductile and readily formed by conventional means.

Welding		Weldable by all of the conventional methods.

Heat Treatment		The alloy is not heat treatable in regard to hardening. It may be annealed if cold working requires such.

Forging		Forging may be done in the range of 2250 F to 1650 F.

Hot Working		Hot work in the range of 2200 F to 1250 F.

Cold Working		The alloy is very ductile and may be readily cold worked. Note that cold working will work harden this alloy and it may be necessary to anneal after extensive cold work.

Annealing		Anneal at 1600 F.

Hardening		Hardens by cold working only.
