Tungsten Bar
Tungsten Bar
Brief introduction:
Zhengzhou Sanhui Co., Ltd selects tungsten powder that that produced by our own factory and then sinters

tungsten bar

by  scientific and standardized technology. Tungsten bar has low content of impurities and good processing performance.
The tungsten density is 18g/cm3-18.3g/cm3 and tungsten purity is more than 99.95%.

The annual output of tungsten bar is small, while, tungsten bar is widely applied. Tungsten bar is made of tungsten powder whose tungsten density is more than 95%.

The melting point of tungsten bar is 3500 ℃. At present, the tungsten ore is mainly distributed in China and Russia. Now, China is the world's largest tungsten export country. Usually, the purity of tungsten bar should be above 99.95%.

The followings are some applications of tungsten bar:

1, Tungsten bar is used to process cutter head, tungsten wire for lighting and various heat conductor.

2, Tungsten bar is applied to make crankshaft of advanced automobile, charge mixture of cylinder and tungsten bar is also used to cast a variety of ingredients of heat resistant steel.

3, Tungsten bar is widely used in the manufacture of artillery, rockets, satellites, aircraft, ships.

Tungsten bar is greatly demanded in the market. The price of tungsten bar varies according to the purity of tungsten bar. There are tungsten bar with the purity of 99.95%, 99.96%, 99.97% and 99.98%. More owners of tungsten bar often wrongly use the tungsten bar in the gold reserve way. Some people would regard the tungsten bar as material property, thus transferring and mortgaging the tungsten bar. This is absolutely a misunderstanding. Tungsten bar is tungsten bar and can not be equated with gold tungsten

Characteristics of tungsten bar:
The melting point of tungsten bar is 3410℃. Tungsten bar has Excellent thermal/electric conductivity. The crystal structure of tungsten bar is impact, so tungsten bar has good erosion resistance.

Applications of tungsten bar:
Tungsten bar is generally used to manufacture emitting cathode, high temperature setting lever, support, lead, print needle and all kinds of electrodes and the quartz furnace heater.

Appearance of tungsten bar:
Tungsten bar has no bending, crack, burr, peeling and other defects affecting the further uses.
