The melting point of an alloy of two (binary) or more metals depends on the relative proportions of the ingredients. An eutectic mixture is the mixture at such proportions that the melting point is as low as possible.
Binary eutectic Molybdenum - Mo - alloys, with composition and melting points are indicated below:
| Alloy Component | Weight of Alloy Component (%) |
Melting Point | |
| K | oF | ||
| Nb - Niobium (Columbium) | 65 | 2570 | 4167 |
| Ni - Nickel | 52 | 1590 | 2403 |
| Os - Osmium | 34 | 2650 | 4311 |
| Pd - Palladium | 57 | 2020 | 3177 |
| Re - Rhenium | 64 | 2780 | 4545 |
| Ru - Ruthenium | 42 | 2200 | 3501 |
| Si - Silicon | 5.7 | 2350 | 3771 |
- T(oC) = 5/9[T(oF) - 32]
