Introduction to nickel applications

Nickel and nickel alloys has good plasticity, corrosion resistance and magnetic properties, so it is mainly used in steel, nickel-based alloy, electroplating and battery and other fields, widely used in aircraft, radar and other military manufacturing, civil machinery manufacturing and electroplating industry.

Iron and steel sector

Because nickel has good corrosion resistance, high temperature resistance, rust resistance and other properties, so it is widely used in stainless steel and alloy steel fields.


Stainless steel

The largest consumption of nickel is in stainless steel, where two-thirds of the world's primary nickel ore is used. Stainless steel containing nickel can not only resist the corrosion of atmosphere, steam and water, but also can resist the corrosion of acid, alkali and salt, so it is widely used in chemical industry, metallurgy, construction and other industries, such as making the required welding vessels, towers, tanks and pipelines in petrochemical industry, textile industry, light industry and nuclear energy industry. Production of urea production of synthetic tower, washing tower, condensing tower, stripping tower and other corrosion resistant high pressure equipment. According to the different proportion of nickel, nickel stainless steel is mainly divided into: austenitic stainless steel, austenitic - ferrite duplex stainless steel, precipitation hardening stainless steel.


Alloy steel

Alloy steel is also called special steel. Due to the different compositions and types of elements, the participation of nickel can improve the strength of the alloy and maintain its good plasticity and toughness. Nickel-containing alloy steel is mainly used in the manufacture of acid-resistant towers, medical devices and daily articles for chemical production, as well as in the mechanical manufacturing, transportation and military industry such as rebuilding Bridges and repairing warships.


Nickel base alloy field

Nickel-based alloy is a kind of alloy with high strength and corrosion resistance at 650 ~ 1000℃. According to the main properties, it can be subdivided into nickel-based heat resistant alloy, nickel-based corrosion resistant alloy, nickel-based wear resistant alloy, nickel-based precision alloy and nickel-based shape memory alloy. Nickel base alloy products mainly include: electric stove, electric iron, turbine engine turbine disc, combustion chamber and turbine blades, color TV, communications equipment, the pendulum clock and measuring tape, manufacturing furniture, have the fine tools, the performance of permanent magnet used on spacecraft automatic open structure, since the motivation of aerospace industrial fasteners and biomedical use artificial heart motor, etc. Widely used in aviation, shipping, chemical industry, electronics, medicine and energy and other industrial fields.
