Carpenter Nickel 200 alloy is a
commercially pure nickel that exhibits
good corrosion resistance. It is
ferromagnetic and has relatively low
electrical resistivity. This combination
of properties has allowed its use in a
wide variety of applications.
Because the alloy displays good
corrosion resistance, it has been used
in food handling equipment, caustic
solution, and general corrosion-
resistant parts and structures. The
magnetic and mechanical properties
have enabled it to be used in devices
requiring magnetic actuated parts.
The excellent combination of
properties enables Carpenter Nickel
200 alloy to be cold worked by
forming and drawing. It is readily
welded and will retain its properties
at both subzero and elevated
temperatures. Its low electrical
resistivity has allowed its use as
conducting leads and terminals in
electrical and electronic components.
Because of its magnetostrictive
properties(specially significant
length change when magnetized), the
nickels have been used in sonic
devices such as sonar or for controls
in ultrasonic welding.
Carpenter Nickel 200 alloys meets the
requirements of ASTM Specification
B-160.

Carpenter Nickel 201 alloy is a low
carbon modification of Carpenter
Nickel 200 alloy that has found
applications in the electronic industry
at temperatures up to 1200°F(649°C).
It is preferred to Carpenter Nickel 200
alloy above 600°F(315°C), because of
its better resistance to "creep."
This alloy has a low annealed
hardness and very low work-
hardening rate that is desirable for
cold forming operations such as deep
drawing, spinning, coining, etc. It has
been used in corrosion-resistant
equipment such as caustic
evaporators, in spun anodes,
combustion boats and laboratory
crucibles, and electronic components
where its excellent fabricating
characteristics provide some
advantage.
