Introduction
Nickel is a silver-white metal, in the air is easy to be oxidized by the air, the surface of the formation of some hair of the oxide film, so people often see the color of nickel hair.Nickel is hard, ductile, magnetic and corrosion resistant, and highly polished.Nickel is also abundant in the earth's crust.Nickel silicate ore or sulfur, arsenic, nickel compounds exist in nature.
The development of nickel
In recent years, the production and consumption of nickel in the world is relatively stable, the supply and demand of nickel in the world market mainly changes with the development of the stainless steel industry. With the increase of the application of nickel in the consumption of stainless steel industry, the smelting technology of ferronickel has made great progress, and the output of high-grade ferronickel has been greatly improved.Russia, Canada, new caledonia, Indonesia, Australia and Cuba account for about 80% of the world's nickel production and exports.
At present, China is the world's largest producer and consumer of Nickel base alloy and iron. With the continuous development of economy and steel industry, the demand for nickel resources is increasing, but at the same time, the output of nickel ore is also increasing, which gradually leads to the severe pattern of global nickel market oversupply.In domestic stainless steel production, the proportion of nickel and iron used as raw materials will increase year by year, and the use of pure nickel will decline.And with the constant development of China's Nickel plating industry at the same time, the question comes, such as nickel more for low grade, proportion of open-pit mining is very small, less recoverable reserves, mining and smelting technology is relatively backward, and also has the very big disparity with the world advanced technology, mining and smelting cost is high, thus, China's nickel industry still has great space for development.
USES of NICKEL METAL PIECE factory
Nickel has good plasticity, corrosion resistance and magnetic properties, so it is mainly used in steel, nickel-based alloy, electroplating and battery fields, widely used in aircraft, radar and other military manufacturing, civil machinery manufacturing and electroplating industry.
Iron and steel sector
Nickel has good corrosion resistance, high temperature resistance, rust resistance and other properties, so it is widely used in stainless steel and alloy steel field.
Stainless steel
The largest consumption of NICKEL METAL PIECE is in stainless steel applications, with two-thirds of the world's primary nickel ore used in the production of stainless steel.Stainless steel containing nickel can resist the corrosion of atmosphere, steam and water, and can resist the corrosion of acid, alkali and salt, so it is widely used in the chemical industry, metallurgy, construction and other industries, such as the production of petrochemical, textile, light industry, nuclear energy and other industries that require welding vessels, towers, tanks, pipelines, etc.Production of urea production in the synthesis tower, washing tower, condensation tower, stripper tower and other corrosion - resistant high-pressure equipment.According to the proportion of nickel, nickel containing stainless steel is mainly divided into: austenitic stainless steel, austenitic - ferrite dual phase stainless steel, precipitation hardened stainless steel.
Nickel base alloy field
Nickel-based alloys are alloys with high strength and corrosion resistance at 650 ~ 1000℃.According to the main properties 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, electronics, medicine and energy industries.
Electroplating field
Nickel plating refers to a layer of steel and other metal substrate covered with a layer of durable, corrosion resistant coating, corrosion resistance than galvanized high 20% ~ 25%.Nickel - plated articles beautiful, clean, and not easy to rust.The processing quantity of electroplating nickel is second only to electroplating, and its consumption accounts for about 10% of the total nickel production.Nickel plating supplier is divided into electroplating nickel and electroless nickel plating.
batteries
Gold-plated nickel is also used in the field of batteries, mainly nickel-hydrogen batteries, cadmium-nickel batteries and nickel-manganese batteries.In recent years, the most rapid development is the application of increasingly practical mhx-ni battery, its advantages are non-toxic green pollution-free, battery storage than nickel-cadmium battery more than 30%, lighter than nickel-cadmium battery, longer service life, the disadvantage is more expensive than nickel-cadmium battery, performance is worse than lithium battery.Mainly used in mobile communications, notebook, video recorder and other fields also used in military, national defense, high-tech and other fields.
