used in over 300,000 products for Wrought Nickel
consumer, industrial, military, transport, Pure nickel UNS N02200 is used in
aerospace, marine and architectural the chemical industry for its corrosion
applications. Nickel has high Electrical resistance - particularly to alkalis. It is
conductivity and high temperature also used for its properties in shielding
resistance. against electromagnetic interference
and in transducers.
Nickel is a critical ingredient in the
lithium-ion batteries used in most Nickel-Iron Alloys
electric vehicles. These are used as soft magnetic
materials, as glass-to-metal seals where high dimensional stability is
and as materials with defined thermal required, such as in precision measuring
expansion properties. instruments and thermostat rods. It is

of thermal expansion around room
temperature. This makes it valuable Nickel-Copper Alloys
Nickel-copper alloys are very resistant
to corrosion by salt water or seawater
and thus find application in marine
applications. The best-known is Alloy
400.

Nickel-Molybdenum Alloys
These are highly resistant to reducing
acids in the absence of oxidizing ions,
such as ferric and cupric or dissolved
oxygen. The best-known is Alloy B-2.
