An alloy is a mixture of metals or a mixture of a metal and an element. Four methods are commonly used to prepare alloys. In the fusion method the alloying elements are used in a fixed proportion and fused together in a refractory melting pot or a brick lined crucible.The metal with a higher melting point is put first then the metal with the lower melting point is added. The metal components are mixed well and allowed to melt.
The molten alloy components are very reactive to the atmospheric oxygen so the molten mass is covered with powdered carbon.to prevent oxidation. The resulting molten mass is left to cool at room temperature.
