Product description:

Tungsten wire is rare in the world a colored minerals, the annual output is very low, very versatile ingredient of material is mainly used for casting. Tungsten ore from a white sand, ore line especially tiny, after mining, milling, water re-election, refining and other multi-channel technology to obtain more than 95% grade tungsten ore, and then through the high-temperature furnace to produce refined shape the finished product is tungsten. Melting point of tungsten: 3500 ℃. Tungsten present mainly in China and Russia, China is now the world's largest exporter of tungsten. Typically the purity tungsten should at 99.95% or more, and must be issued by authority of the examination and analysis test reports, for example: non-ferrous metals and electronic materials analysis and testing center analysis test report.
