Nickel-copper-aluminum alloy, UNS N05500 is used where a combination of
high strength and resistance to corrosion are involved. For optimum
tool life the annealed condition is recommended. Cold drawn material is
intended for automatic machining operations.
Nickel-copper-aluminum alloy sheet and strip in the annealed condition
may be used in the manufacture of articles in which heading, bending,
curling, drawing, forming, lock-seaming, welding, etc., operations are
involved.
Cold rolled strip of half hard and full hard temper are used where
light deformations or liberal bending radii are involved, for
applications such as springs,
Nickel-copper-aluminum alloy wire in the annealed condition is intended
for severe forming, cold heading, and roll threading operations.
Nickel-copper-aluminum alloy wire, spring temper in the as drawn
condition is intended for coiling of helical springs which are to be
aged hardened after coiling in order to obtain maximum strength and
hardness. Where helical springs are to be cold pressed, the cold
pressing is to be done
after coiling and aging.
