Tungsten Copper Melting Point

The influencing factors of tungsten copper melting point：

1.The tungsten copper melting point usually refers to under atmospheric pressure, the melting point varies with pressure, it can divided into two different situations, When the pressure increases, the melting point increases when the pressure increases, but the liquid is different from the tungsten copper, the melting point is reduced when the pressure increases.

2. Tungsten copper products are generally have impurities, even a small amount of tungsten copper, the change of its melting point are very large.

In nature, the melting point of tungsten copper is the coexistence of tungsten and copper in solid and liquid at a certain temperature. In the same crystal, melting point relate to pressure, under a certain pressure, the melting point and freezing point are the same, when the volume expansion of the material in the melting pressure, its melting point increases when the pressure increases.

The melting point of tungsten copper is measured by micro melting point method and capillary method. However, it is usually measured by professional measuring instrument in practical.
