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.
