Nickel Permanickel 300 (tm)

Aging Procedure

See "Heat Treat".

Annealing Procedure

Anneal at 2000 F and water quench.

Applications

Typically used for electrical contact applications such as springs.

Cold Workability

The alloy readily cold works by conventional means.

Forgeability

Forging may be done at 2200 F to 1700 F. Note that after forging a solution anneal must be done -- see "Annealing".

Formability

Easily formed by conventional means.

Hardening Procedure

Hardens due to cold working and aging - see "Heat Treat". A combination of cold working and aging will produce the greatest tensile strength.

Heat Treatability

Solution anneal at 2000 F and water quench. This is followed by the aging treatment at 910 F for 16 hours and furnace cool.

Hot Workability

Hot working may be done in the range of 2200 F to 1200 F. Note that after hot work a solution anneal must be done -- see "Annealing".

Machinability

May be readily machined by conventional means, although machining is best when the alloy is in the age-hardened condition.

Other Mechanical Properties

In the age-hardened heat treat condition the tensile properties are approximately 50% greater and the elongation is reduced by about 50% in comparison to the annealed values shown.

Principle Design Features

This is an age-hardenable, high nickel content alloy, with very good thermal and electrical conductivity.

Weldability

Fusion welding is not recommended due to the composition of the alloy. Electric resistance welding may be used.
