Table of melting temperatures of different metals, and at what degrees they melt

Each metal and alloy has its own unique set of physical and chemical properties, among which the melting temperature takes not the last place. The process itself means the transition of the body from one state to another, in this case, from solid crystalline state to liquid. To melt metal, it is necessary to bring heat to it before reaching the melting point. With it, he can still remain in a solid state, but with further exposure and increased heat, the metal begins to melt. If the temperature is lowered, that is, remove some of the heat, the element hardens.

The highest melting point among metals belongs to tungsten: it is 3422Co, the lowest is in mercury: the element melts at 39Co. Determine the exact value for alloys, usually, does not represent a possibility: it can vary considerably depending on the percentage of components. They are usually written as a numerical interval.

How it happens

Melting of all metals is approximately the same - by external or internal heating. The first is carried out in a thermal furnace, for the second use resistive heating when passing an electric current or induction heating in a high-frequency electromagnetic field. Both options affect the metal approximately equally.

As the temperature increases, the amplitude of thermal oscillations of molecules also increases, there are structural defects of the lattice, expressed in the growth of dislocations, jumping atoms and other violations. This is accompanied by the rupture of interatomic bonds and requires a certain amount of energy. At the same time, a quasi-liquid layer is formed on the surface of the body. The period of destruction of the lattice and the accumulation of defects is called melting.

Separation of metals

Depending on the melting point of metals are divided into:
