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 components in stainless steel and improves its corrosion resistance and mechanical properties.
Electroplating: Due to its good corrosion resistance and appearance, nickel is often used to electroplat other metals to provide anti-corrosion and decorative effects.
Battery Manufacturing: Nickel is an important material in many types of batteries, including nickel-cadmium and nickel-metal hydride batteries.
Industrial Catalysts: Nickel is used as a catalyst to accelerate certain chemical reactions, such as the hydrogenation of oils and fats.
Currency Manufacturing: Due to its durability and unique color, nickel or its alloys are used to manufacture coins.
Specialty Alloys: Nickel-based alloys remain stable under high temperatures and extreme pressures and are used in the aerospace, chemical and energy industries.
