Alloy material is metal material.
An alloy is a solid product with metallic properties obtained by mixing one metal with another metal or metals or a variety of non-metals, melting, cooling and solidifying. Depending on the number of constituent elements, they can be categorized as binary alloys, ternary alloys and multi-element alloys. The formation of alloys usually improves the properties of the elemental elements.
For example, steel is stronger than its main constituent element, iron. The physical properties of an alloy, such as density, reactivity, Young's modulus, electrical and thermal conductivity, may be similar to those of the alloy's constituent elements, but the tensile and shear strengths of an alloy are usually the same as the properties of the constituent elements. There is a great deal of variation. Unlike pure metals, most alloys do not have a fixed melting point.
Types
(1) Mixture alloys (****melt mixtures), alloys in which the components that make up the alloy crystallize separately when the liquid alloy solidifies, e.g., solder, bismuth-cadmium alloys.
(2) solid-melt alloys, alloys that form a solid solution when the liquid alloy solidifies, such as gold and silver alloys.
(3) metal intercalation alloys, alloys in which the components form compounds with each other, such as brass (β-brass, γ-brass and ε-brass) composed of copper and zinc.
