A master alloy is a base metal such as aluminium, copper or nickel combined with a relatively high percentage of one or two other elements. An example is AlTi10 - a binary alloy consisting of 10% titanium in aluminium. A master alloy is a semi-finished product. It is manufactured for use as a raw material by the metals industry. Master alloys are produced in various shapes. Examples are: ingot, waffle plate, rod in coils, etc. Master alloys are used worldwide. Invariably they are found in plants where metal is melted, alloyed with various elements and then cast into shapes. This can be aluminium, iron, steel or even a precious metal such as gold.

In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer.
