The process of making alloys involves ( Heating ) pure metals to remove impurities. Then the pure metals are(mixed) with other components. An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character.

Explanation:

The preponderance of alloys are produced by combining metals in the molten state; then the mixture is poured into metal or sand molds and delivered to harden. Usually, the major ingredient vanishes first; then the others are assigned to it and should presently dissolve.
