◆ Features
Pure nickel is a silver-white metal with a density of 8.9g / cm3 and a melting point of 1453 ° C. Because the surface is oxidized to form a dense and strong protective film at normal temperature, it has excellent corrosion resistance; pure nickel has excellent welding performance and processing performance, and can be processed into products such as tube rod wire plate strip foil.
Pure nickel materials have good corrosion resistance in NaOH solutions at any concentration and temperature and in molten NaOH above 400 ° C. Pure nickel materials have good corrosion resistance to Na2O2, Na2CO3, NaHCO3, and alkaline solutions or molten liquids containing KNO3.
◆ Use
Chemical equipment such as pipes, heat exchangers, evaporators, heaters, reaction kettles, etc .; targets for various coatings; electrodes, etc.
