Nickel is used in large quantities to make various types of stainless steel and soft magnetic alloys (which can be simply understood as: magnetic alloys that are easily magnetized under the action of an external magnetic field, and the magnetic induction intensity (magnetic induction) basically disappears after the external magnetic field is removed. The main ones we are talking about here It is a nickel-iron soft magnetic alloy.) and alloy structural steel.

Nickel and chromium, copper, aluminum, cobalt and other elements can form heat-resistant alloys, electrical alloys and corrosion-resistant alloys.

Nickel-chromium alloy (such as Ni-Cr20) has high heat resistance and large resistance. Thermoelectric bodies (resistance wires) made of it can be used as electric heating elements in electric furnaces, electric soldering irons, electric irons, etc., and can operate at 1100℃ It can work under long-term conditions; although Ni-Cr9 and Ni-Cr10 have slightly poor heat resistance, they have high resistance, small temperature coefficient of resistance, and large thermal electromotive force, so they are good materials for thermocouples.

Nickel-based heat-resistant alloys are mainly used for turbine engine turbine discs, combustion chambers and turbine blades. The famous “Monel” alloy is a corrosion-resistant nickel alloy containing copper, iron and manganese. It has high strength, good plasticity and corrosion resistance. It has become an important material in the manufacturing industry of electrical appliances, ships and medical devices.

Nickel-silicon alloy is often made into wires, strips, and rods for use in electron tubes and electric vacuum instruments.

Nickel iron and nickel cobalt alloy are good magnetic materials. Nickel is the main material for the production of nickel-cadmium, nickel-hydrogen batteries and nickel mesh. At the same time, nickel is also widely used in electroplating and catalyst production.
