Good machinability, good mechanical properties, high modulus of elasticity, harmless to the health and environment.
1) Product Description:
Tungsten deposit is the world's rare in a non- ferrous minerals, low output, uses a very wide range, the main ingredients for casting materials used. Tungsten gold from a white sand ore, ore line in particular small, after extraction, grinding, water re- election, refining and other multi- channel technology, has been more than 95% grade tungsten powder, and then after a high temperature furnace to produce refined shape The finished product is the tungsten deposit. The melting point of tungsten deposit: 3500 . At present, wolframite are mainly distributed in China and Russia, and China is now the world's largest exporter of tungsten deposit. Tungsten is usually the purity of gold should be more than 99. 95 percent, but must be issued by the inspection authority analysis of test reports, for example: National Non- Ferrous Metals and Electronic Materials Analysis Test Center analysis of test reports.
(B) Product use:
1, processing car Knife Blade, lighting equipment using thermal conductivity of tungsten wire and various body
2, manufacturing of advanced automotive crankshaft, cylinder ingredients, heat- resistant steel casting a variety of ingredients
3, are widely used in military, artillery, rockets, satellites, aircraft, ship manufacturing
(C) Product :
Usually divided into: 12 mm ? 12 mm ? 300 mm , 10 mm ? 10 mm ? 360 mm form of strips that we have always been referred to tungsten gold bars. Each approximately 1Kg, generally divided into small packages and large packages. Usually small packing cartons or plastic box packaging, in kilograms per box is about 8 dollars a box. Large wooden box packaging units to 10 kilograms of usually 6- 8 for a box of cartridges.
(D) Product prices
Currently on the market turnover low, prices mixed tungsten plus the price of gold itself is very expensive on the market price so it is difficult reunification. On the current situation, tungsten gold prices mainly to distinguish between the purity, and because the reasons for the use of the owner of more gold reserves is a way to use tungsten deposit is generally regarded as the transfer of tangible assets such as mortgages. Currently on the market sold the most is the following purity tungsten deposit:
Purity: 99. 95% Price : 2- 30000 / kg
Purity: 99. 96% Price : 4- 50000 / kg
Purity: 99. 97% Price: 10 million / kg
Purity: 99. 99% Price: 17 million / kg
