Características: Nickel 200 is commercially pure wrought nickel. It is highly resistant to various reducing chemicals. It can also be used in oxidizing conditions that cause the formation of a passive oxide film, for instance its unexcelled resistance to caustic alkalis. Nickel 200 is limited to service at temperatures below 315℃, because at higher temperatures it suffers from graphitization which results in severely compromised properties. In that circumstance, Nickel 201 is used instead. It has a high Curie temperature and good magnetostrictive properties. Its thermal and electrical conductivities are higher than nickel alloys.
Aplicações: Useful for applications where maintaining product purity is considered such as handling of caustic alkalis, foods and synthetic fibers; electrical and electronic parts; aerospace and missile components; and chemical storage and shipping tanks.
