Nickel And Nickel Alloys
Nickel is a versatile, highly corrosion resistant element that will alloy with most metals. Due to its corrosion resistance, nickel is used to maintain product purity in the processing of foods and synthetic fibers. It is highly resistant to various reducing chemicals and is unexcelled in resistance to caustic alkalies. In addition, nickel has good thermal, electrical and magnetostrictive properties. Relatively high thermal conductivity of this metal has lead to its frequent use for heat exchangers
Commercially pure or low-alloy nickel may contain very small amounts of alloying elements to absolutely none. By contrast nickel alloys contain significant amounts of added elements. Nickel and nickel alloys are both non-ferrous metals that are useful in a range of applications, most of which involve corrosion resistance and/or heat resistance.
