in caustic alkali, in the 50% boiling caustic soda solution, the annual corrosion rate of nickel will not exceed 25 microns. The strength and plasticity of nickel are also very good, which can withstand a variety of pressure processing.
Nickel plate is used to make various types of stainless steel, soft magnetic alloy and alloy structural steel. Nickel is the main material of nickel cadmium, nickel hydrogen battery and nickel net. Nickel is also widely used in electroplating and catalyst production. Nickel, chromium, copper, aluminium and cobalt elements can form heat-resistant alloy, electrical alloy and corrosion resistant alloy. Nickel chromium alloy has high heat resistance and high resistance, it can be used as the pyroelectrics (resistance wire), it also can be used as electric furnace, electric iron, electric iron heating element, it can work at 1100 degrees. Although the heat resistance of Ni-Cr10 and Ni-Cr9 is slightly worse, the resistance is big, the resistance temperature coefficient is small, the thermoelectric power is big, it is the good material of the thermocouple. Nickel base heat resistant alloy is mainly used as turbine disc of turbine engine , combustion chamber and turbine blade. Famous "Monel alloy contains copper, iron and manganese nickel alloy, it has high strength, good plasticity, corrosion resistance, it is also the important materials of electrical, ships and medical device manufacturing industry.
