Home / Refractory Metals
Explore refractory-metal families, compare material choices and find the product form your project needs.
Start with material and operating conditions, then specify grade, dimensions, quantity and drawing or acceptance requirements.
Selected starting points; the complete directory below retains all existing material families.

Browse these nine material families, covering the classical refractory metals and related engineering metals. Each requires its own grade, product form and service conditions. For iridium, ruthenium and chromium purchasing routes, visit the Rare Metals directory.
These verified routes are examples or broader form-family pages. Choose the material family above to compare the same form in other metals.
| Grouping | Catalog meaning | Engineering check |
|---|---|---|
| W, Mo, Ta, Nb, Re | Classical refractory-metal grouping. | Compare temperature, atmosphere, load, creep, recrystallization, joining and contamination limits for the exact grade. |
| Zr, Hf, Ti, V | Related reactive or high-melting engineering metals in this catalog. | These are not all above a single 2,000°C melting threshold and cannot share one strength or oxidation rating. |
| Cr, Ru, Ir | Additional existing high-melting/specialty material families. | Select by chemistry, process, form and operating environment rather than group label alone. |
| Metal, alloy and ceramic | Pure metal, named alloy, carbide/oxide/nitride are different material systems. | A refractory lining ceramic is not a refractory metal, and a compound does not inherit elemental-metal mechanical properties. |
Approximate elemental melting and boiling values retained from the existing comparison. Reference sources and measurement conditions can differ; these are not maximum working temperatures or guaranteed properties of an alloy or supplied part.
| Element | Melting reference, °C | Boiling reference, °C |
|---|---|---|
| Tungsten | ~3422 | ~5555 |
| Molybdenum | ~2623 | ~4639 |
| Tantalum | ~3017 | ~5458 |
| Niobium | ~2477 | ~4744 |
| Rhenium | ~3186 | ~5596 |
| Zirconium | ~1855 | ~4409 |
| Hafnium | ~2233 | ~4603 |
| Vanadium | ~1910 | ~3407 |
| Titanium | ~1668 | ~3287 |
| Ruthenium | ~2334 | ~4150 |
| Iridium | ~2446 | ~4428 |
Hot air, oxygen, vacuum, inert gas, process gases and contact media change oxidation and corrosion behavior. A high melting point does not establish oxidation resistance, universal acid resistance or suitability for a furnace atmosphere.
State stress, operating temperature and duration, permitted deformation, grain structure, recrystallization/heat-treatment condition and joining requirements. Creep is time-dependent; density alone does not establish resistance.
Confirm dimensions, tolerance, surface, formability, ductile-to-brittle behavior where relevant, machining allowance and weld/joint design. Manufacturing route and condition can change strength and durability; one generic tensile value is insufficient.
Furnace and crystal-growth parts, deposition sources, chemical-service equipment, electronics and aerospace/medical research need different acceptance criteria. Ceramic furnace linings belong to a separate refractory-material category. Specify grade, chemistry, inspection, traceability and any destination/end-use review required.
