According to the name of the main metal with large content in the alloy, it is classified as a certain alloy. For example, the copper alloy with high copper content has the properties of copper.
Alloy type
(1) Mixed alloy (eutectic mixture): when the liquid alloy solidifies, the components constituting the alloy crystallize separately, such as solder, bismuth cadmium alloy, etc;
(2) Solid melt alloy, the alloy that forms solid solution when the liquid alloy solidifies, such as gold and silver alloy;
(3) An alloy in which components form compounds with each other, such as copper and zinc（ β- Brass γ- Brass and ε- Brass), etc.
Alloy is superior to pure metal in many properties, so it is mostly used in application materials (see ferroalloy and stainless steel).
