WebApr 4, 2024 · Uses of Alloys. Besides being used in their pure form, metals are also often used in the form of their alloys. An alloy is a homogenous mixture of two or more metals, or a metal and a non-metal. By adding appropriate amount of other metals, or non-metals, to form the alloys, the properties of a given metal can be (significantly) modified.
