Main elements
| Tantalum (Ta) | ≥ 99.9 % (UNS R05200, pure) |
|---|---|
| Tantalum (Ta) – technical grade | ≥ 99.5 % |
| Ta-2.5W alloy (R05252) | W 2 – 3.5 % |
| Ta-10W alloy (R05255) | W 9 – 11 % |
| Niobium (Nb) | typical traces ≤ 0.1 % |
| Impurities (Fe, Mo, W, O) | traces |
Indicative values: distinguish between pure tantalum (≥ 99.9 %), technical grades and Ta-W alloys; niobium and oxygen content affects the valuation. The quality is certified by analysis for each batch.
Physical and mechanical data
| Density | 16.69 g/cm³ |
|---|---|
| Melting temperature | ≈ 3017 °C |
| Hardness | ≈ 80 – 120 HV (annealed) |
| Elastic modulus | ≈ 186 GPa |
| Corrosion resistance | outstanding: inert to acids (except HF) up to high temperatures |
| Structure | body-centred cubic (BCC) |
Annealed tantalum is very ductile; properties depend on the supply condition (annealed, work-hardened, sintered).
