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
