Tungsten
Purchase of scrap and turnings of metallic tungsten: electrodes, sheets, wires, contacts and residues from vacuum furnaces. Fast quotations and collection throughout the territory.
Metallic tungsten (element W): a refractory metal with the highest melting point among metals, very high density and hardness. Reference markets: electrodes, lighting, electronics, vacuum furnaces and heavy alloys.
- Forms electrodes · wires · sheets · turnings
- Density 19.25 g/cm³
- Melting ≈ 3422 °C
Main elements
| Tungsten (W) | ≥ 99.9 % (pure grade) |
|---|---|
| Tungsten (W) – technical grade | ≥ 99.5 % |
| Doping oxides (ThO₂ / CeO₂ / La₂O₃) | doped electrodes (≈ 1 – 4 %) |
| Carbon (C) | ≤ 0.01 % (pure grade) |
| Metallic impurities (Fe, Mo, Ni) | traces |
Indicative values: distinguish between pure tungsten (≥ 99.9 %), technical grades and electrodes doped with oxides (thoriated, ceriated, lanthanated). The quality is certified by analysis for each batch.
Physical and mechanical data
| Density | 19.25 g/cm³ |
|---|---|
| Melting temperature | ≈ 3422 °C (the highest among metals) |
| Hardness | ≈ 350 – 500 HV (annealed/sintered) |
| Elastic modulus | ≈ 400 – 410 GPa |
| Thermal expansion coeff. | ≈ 4.5 µm/m·K (very low) |
| Structure | body-centred cubic (BCC) |
Mechanical properties depend on the state (sintered, annealed, worked).
