Commercially pure nickel alloys contains at least 99% of nickel (Ni).

The alloys may also contain small amounts of cobalt (Co) and such impurities like manganese (Mn), iron (Fe), silicon (Si), copper (Cu).

The alloys are non-heat-treatable and may be hardened by cold work.

Some alloys (301) contain also minor alloying additions of aluminum (Al) and titanium (Ti).The alloys, containing these elements, are heat-treatable and may be strengthened by precipitation hardening. They are used for parts that require a high level of mechanical strength such as bolts and springs.

Commercially pure nickel has good corrosion resistance in oxidizing media and excellent corrosion resistance in alkaline solutions, non-oxidizing acids and halogen gases.

Commercially pure nickel possesses high thermal and electrical conductivity.

Commercially pure nickel is used for manufacturing food processing equipment, chemicals containers, caustic handling equipment, electrical and electronic parts, anodes for electroplating, heat exchangers, fluorescent lamps, decorative and protective coating.
