Nickel is used to produce various types of stainless steel and soft magnetic alloy. Here we mainly talk about the nickel iron soft magnetic alloy and alloy structural steel, nickel plate.
 
Nickel and chromium, copper, aluminum, cobalt and other elements can be composed of heat-resistant alloy, electrical alloy and corrosion resistant alloy, etc. Ni Cr alloy (such as Ni-Cr20) have high heat resistance and high electric resistance, it can be produced into pyroelectrics (the resistance wire), which can be used as electric heating element in electric stove, electric iron, it also can work at 1100 degrees for a long time. Although the heat resistance of Ni-Cr9 and Ni-Cr10 is slightly worse, it has big resistance, small resistance temperature coefficient and big thermoelectric potential, which is the good material of the thermocouple. Nickel based heat resistant alloys are mainly used for turbine engine turbine disc, combustion chamber and turbine blades and so on. The famous "Monel Alloy" includes copper, iron and manganese nickel alloy, which has high strength, good ductility and corrosion resistance and become an important material in medical appliances, ship manufacturing industry.
 
The above is the basic knowledge of the nickel plate I explained to you, if there is any question, welcome to inquire.
