Production of tungsten rolled products
Technical characteristics
Tungsten has excellent mechanical properties: hardness, wear resistance, immunity to extreme heat, minimum thermal expansion coefficient, good thermal conductivity, exceptional resistance to thermal creep, and a very high modulus of elasticity.
Fabrication
Technological ductility of tungsten is minimal, but increases when the billet is heated, so tungsten semi-finished products are produced by hot pressure machining. At first, the billets are produced by powder metallurgy, which is then processed according to a special technology.
Grades of tungsten alloys
| Mark | Additives | The purpose of the additive |
|---|---|---|
| HF | Without additive | - |
| VA | Si + Al | Increase of primary recrystallization temperature, strength and form stability after annealing |
| BM | Si + Th | Increase of recrystallization temperature and strength. |
| VT | ThO2 | Increase of emission properties of tungsten |
| VI | Y2O3 | --- "--- |
| VL | LaO | --- "--- |
| BP | Re | Increase of plasticity of tungsten after high-temperature treatment, increase of primary recrystallization temperature, strength |
| BPH | Increased content of impurities | - |
| MB | Mo | Increased strength while retaining ductility after annealing |
