Nickel-iron chemical composition

Nickel-iron, silicon phosphorus sulfur content is low, the surface of clean, nickel-point enough, composition and stability.
Symbol: Ni; Color: silver-white; Density: 8.90, melting point: 1455; Boiling point: 2913
Nickel is a silvery white magnetic metal of iron. Ancient Egypt, China and the Babylonians had to use a high nickel content iron meteorite as objects. Can be said that nickel is both "old" "too young" metal, nickel has the magnetism, in the steel industry as a gold-bearing elements of additives can improve the bending degree and hardness of steel in the cast iron can be uniform in its structure, density increased also be used as nickel or chromium cast iron, and other casting alloys by adding agents. The main component of many magnetic materials; nickel also has good antioxidant activity. In air, the nickel surface of the NiO film, can prevent further oxidation. Experiments show that the purity of 99% of nickel, rust does not occur within 20 years. Corrosion resistance of nickel is also strong, especially in caustic alkali resistance to corrosion in 50% of boiling caustic soda solution, the corrosion rate of nickel per year less than 25 microns. Strength and plasticity of nickel is also very good, can withstand all kinds of pressure processing, at present, the main raw material is nickel, nickel sulfide ore, followed by the oxidation of mine. In addition, the existence of manganese nodules in the seabed will also be known as the mention of nickel important resource.
We selected from the Indonesian laterite ore to refining processing, is mainly engaged in the production and sales of nickel-iron. The company always pay attention to product quality management to genuine, puerile, the principle of good faith management, customer first for the purpose of, the products sold at home and abroad, has a good reputation in the market. We sincerely welcome friends at home and abroad come to discuss the purchase and sale business, a total of sac-setting effort.
