Density:8.91g/cm3
Melting point: 1728 K (1455 oC)
Boiling point: 3263 K (2990 oC)
Discovered:
Nickel has been used since ancient times. Pure nickel was extracted by Axel Cronstedt from the ore niccolite (nickel arsenide, NiAs) in 1751. The element name comes from comes from the German word 'kupfernickel' meaning Devil's copper.
Characteristics:
Nickel is a hard, silvery-white metal, which is malleable and ductile. The metal can take on a high polish and it resists tarnishing in air. Nickel is ferromagnetic and is a fair conductor of heat and electricity. Most nickel compounds are blue or green.
Uses:
Nickel is used in corrosion-resistant alloys, such as stainless steel. (Stainless steel is the application in which most nickel is used.)
Tubing made from a copper-nickel alloy is used in desalination plants. This alloy is naturally resistant to corrosion by seawater and to biofouling. Many coins contain nickel. Nickel steel is used for burglar-proof vaults and armour plate. Nickel is also used in batteries - for example NiCd (nickel-cadmium) rechargeable batteries - and in magnets.
We are in the position of producing all Grades of Nickel in according with ASME standards equivalents.
