Nickel
Pure nickel is a silvery white metal. Because the surface is oxidized at room temperature to form a dense and tight protective film, it has excellent corrosion resistance. Pure nickel has excellent kneading performance and processing performance, and can be processed into tubes, rods, wires, plates, strips, foils and other products.
Pure nickel material has good corrosion resistance in any concentration and temperature of NaOH solution and molten NaOH above 400°C. Pure nickel materials have good corrosion resistance to Na2O2, Na2CO3, NaHCO3 and alkaline solutions or molten liquids containing KNO3.
