Nickel
镍
Nickel is a white metal, with a faint tinge of yellow. It is used widely in making alloys, including copper-nickel (75% copper, 25% nickel) which is used in coinage.
镍是一种白色金属，略带黄色。它广泛用于制造合金，包括铜镍合金（75%铜，25%镍），用于铸造货币。
Nickel is used in the production of the strongly ferromagnetic alloy alnico which is used to make strong permanent magnets. Alnico alloys iron, nickel, cobalt and aluminum.
镍用于生产强铁磁性合金alnico，该合金用于制造强永磁体。alnico合金含有铁、镍、钴和铝。
Stainless steel contains 12-18% chromium and usually about 8% nickel.
不锈钢含12-18%的铬，通常还有约8%的镍。
Iron objects can be plated with nickel for corrosion resistance.
铁制物体可以镀镍以提高抗腐蚀性。
The principal ores of nickel are nickelite (NiAs), millerite (NiS), and pentlandite ((Ni,Fe)S. Nickel forms a sulfide mineral with arsenic called gersdorffite. Nickel forms another arsenide called nickel-skutterudite, NiAs2-3. The sulfide formed with antimony is called ullmannite. Copper, cobalt and nickel join in the sulfide carrollite, Cu(Co,Ni)2S4. Cobalt and nickel form the sulfide siegenite, CoNi2S4. Nickel is often found in association with iron and sometimes forms the compound Ni3Fe, called awaruite in its mineral form. Nickel-iron meteorites are fairly common. A major source of nickel is the Sudbury Basin in Canada associated with the second largest meteoritic impact crater on the Earth.
镍的主要矿石是镍矿石（NiAs）、米尔勒石（NiS）和pentlandite（(Ni,Fe)S）。镍形成一种含硫和砷的矿物，称为gersdorffite。镍还形成另一种砷化物，称为nickel-skutterudite，化学式为NiAs₂-₃。与锑形成的硫化物称为ullmannite。铜、钴和镍共同形成硫化物carrollite，化学式为Cu(Co,Ni)₂S₄。钴和镍形成硫化物siegenite，化学式为CoNi₂S₄。镍常与铁共生，有时形成化合物Ni₃Fe，称为awaruite。镍铁陨石较为常见。镍的重要来源是加拿大的Sudbury Basin，该地与地球上第二大的陨石坑有关联。
Nickel is used in alloy with gold to make "white gold" for jewelry use.
镍用于与黄金合金以制作“白金”用于珠宝用途。
