Hard, wear-resistant, chemically inert, chemically resistant, and nearly impervious to hydrogen at high temperatures, refractory carbides can be formed by chemical vapor deposition at temperatures as low as 10% of their melting point. Ultramet offers the following materials, along with other carbides, nitrides, and silicides:
| Carbon (C) | Zirconium carbide (ZrC) |
| Hafnium carbide (HfC) | Silicon carbide (SiC) |
| Tantalum carbide (TaC) | Boron carbide (B4C) |
| Hafnium carbide (HfC) | Titanium carbide (TiC) |
| Niobium carbide (NbC) |
