Nickel
Nickel (niè), English name Nickel, element symbol Ni, located in the fourth period, eighth group, atomic number 28. Nickel is a silvery white metal with good mechanical strength and ductility. It is insoluble in water, has strong corrosion resistance to acids and alkalis, and is resistant to high temperatures. The melting point is 1455℃, and the boiling point is 2730℃. The density is 8.902g/cm³. It can be used to make currency, etc., and can also be plated on other metals to prevent rust.
Main Applications of Nickel
Stainless Steel Manufacturing: Nickel is one of the key ingredients in stainless steel, which improves the corrosion resistance and mechanical properties of stainless steel.
Electroplating: Because nickel has good corrosion resistance and appearance, it is often used to electroplate other metals to provide anti-corrosion and decorative effects.
Battery Manufacturing: Nickel is an important material in many types of batteries, including nickel-cadmium batteries and nickel-metal hydride batteries.
Industrial Catalysts: Nickel is used as a catalyst to speed up certain chemical reactions, such as the hydrogenation of oils and fats.
Currency Manufacturing: Nickel or its alloys are used to make coins due to its durability and unique color.
Specialty Alloys: Nickel-based alloys remain stable under high temperatures and extreme pressures and are used in the aerospace,
chemical, and energy industries.
Electronic Components: Nickel is also used in certain types of electronic components, such as magnetic heads and resistors.
