High-melting-point metal sheets and foils
Tungsten (W), tantalum (Ta), niobium (Nb) and zirconium (Zr) all melt above 1850°C and are chemically stable, for vacuum furnace heating elements, sputtering targets, nuclear materials research and advanced semiconductor processes. This page offers a standard size of 100 × 100 mm, with foils as thin as 0.02 mm.
Material comparison
| Material | Melting point (°C) | Density (g/cm³) | Key properties | Typical uses |
|---|---|---|---|---|
| High-purity tungsten (W) | 3422 | 19.3 | High melting point, very hard | Vacuum furnace heating elements, electron gun filaments, sputtering targets |
| High-purity tantalum (Ta) | 2996 | 16.7 | Resists strong acids, good biocompatibility | Electrolytic capacitors, medical implants, chemical equipment |
| High-purity niobium (Nb) | 2477 | 8.6 | Superconducting, low thermal neutron cross-section | Superconducting magnets, nuclear reactors, Nb₂O₅ thin-film research |
| High-purity zirconium (Zr) | 1855 | 6.5 | Neutron-transparent, corrosion-resistant, low thermal expansion | Nuclear fuel cladding, chemical valve parts, research foils |

Ultra-thin foils (≤ 0.1 mm)
- 0.02–0.1 mm are common laboratory foil thicknesses; please confirm the thickness you need before ordering.
- For non-standard sizes (other than 100 × 100 mm), please ask; custom cutting is available for some materials.
