Applications
Type 200
Nickel 200 is a ferromagnetic, wrought commercially pure nickel with
high ductility across wide temperature ranges. It also provides good
corrosion resistance against moderately reducing environments. In the
annealed condition it has roughly the strength of mild steel. Material
provided in the as rolled condition can provide higher strength levels.
Type 205
Nickel 205 is similar to type 200 with the exception that its
composition has been enhanced for use in electrical and electronic
applications. It is commonly used in anode and grids for electronic
valves, lead wires, battery cases, transistor housings and
magnetostrictive transducers.
Type 220
Nickel 220 is chemically similar to type 205 but it has been further
enhanced to work specifically in the area of electronic tube cathodes.
Type 233
Nickel 233 is a wrought commercially pure nickel with a low carbon
content. It has excellent corrosion resistance with high electrical and
thermal conductivities. It is most suitable for use in electronic
components and temperature sensors.
Type 270
Nickel 270 is the highest purity of the nickel alloys and is made by
powder metallurgy. It has a low base hardness but holds high ductility. It
high purity makes it useful for hydrogen thyratrons and electrical
resistance thermometers.
