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 where the melting point is as low as possible
Binary eutectic Gold - Au - alloys, with composition and melting points are indicated below:
| Alloy Component | Weight of Alloy Component (%) | Melting Point | |
