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.
(Two) Product Use:
1, processing car knife blade, lighting equipment and a variety of thermal conductivity with tungsten
2, advanced automobile crankshafts, cylinder ingredients, heat-resistant steel casting various ingredients
3, widely used guns, artillery, rockets, satellites, aircraft and ship
(Three) Specifications:
Usually divided into: 12mm × 12mm × 300mm, 10mm × 10mm × 360mm strip form is that we often mentioned tungsten bars. Each about 1Kg, generally divided into small packages and large packaging. Usually small packing carton or plastic box packaging, pack in kg is about 8 box. Bulk use of wooden units in ten kilograms of usually 6-8 box is a box.
