Just as a restaurant chef uses a small amount of seasoning to adjust dishes, the metal industry uses master alloys to adjust the performance of its products.

The master alloy is a base metal, such as aluminum, copper or nickel, with a relatively high ratio of combination with one or two other elements. For example, AlTi10-a binary alloy that contains 10% titanium in aluminum. Master alloy is a semi-finished product. The metal industry manufactures it as a raw material. The master alloy can be made into various shapes. For example:  ingots, waffle, wire rods, etc.

Master alloys are widely used worldwide. In the factory, metal is melted, various elements are added, and then cast into various shapes. It can be aluminum, iron, steel, or even precious metals such as gold.

There are various reasons for adding the main alloy to the melt. One of its main applications is to adjust the composition, that is, to change the composition of the liquid metal to achieve the required chemical specifications. Another important application is structure control-influencing the microstructure of the metal during casting and solidification to change its properties. These properties include mechanical strength, ductility, electrical conductivity, castability or surface appearance. The master alloy is sometimes called "hardener", "grain refiner" or "improver", depending on its application.

The reasons for using master alloys instead of pure metals may be economic, technical, or both. When some elements are added in pure form, the loss rate is high and the yield is low. Others will not dissolve at all at the furnace temperature. Master alloys usually provide a solution because it dissolves faster at lower temperatures, saving valuable energy and production time.
