Tungsten Bar
Brief Introduction of Tungsten Rod:
Tungsten rod 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%.
Tungsten bar is widely applied.
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%.
Tungsten rod chemical compositions and applications:
| type | purity of tungsten | application |
| WAL1 | >=99.92% | filament,cathode and components for electron tubes,electrode for the gas discharge tube.etc. |
| WAL2 |
| WAL3 | >=99.92% | grid siderod,lead,support,electrode for the discharge lamp,etc. |
| W1 | >=99.95% | grid siderod,support,lead and electrode,etc. |
| W2 | >=99.92% |
Tungsten bar forms and dimensions:
| furnished form | specified diameter | min.length |
| wroughted | 2.8<=d<5.0 | 600 |
| 5.0<=d<6.5 | 300 |
| 6.5<=d<11.0 | 200 |
| straightened | 0.8<=d<1.0 | 1000 |
| 1.0<=d<3.0 | 800 |
| ground | 0.8<=d<3.0 | 800-1000 |
| 3.0<=d<6.5 | 300-600 |
| 6.5<=d<10.0 | 200 |
Applications of tungsten rod:
1, Tungsten rod 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.
Tungsten bar has no bending, crack, burr, peeling and other defects affecting the further uses.
Customized tungsten parts are available.
