What is the master alloys?>

Usually the metal industry will use the master alloys to adjust the properties of its products, such as magnesium alloy, aluminium alloy and copper alloys.

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. Such as  MgGd30 - a master alloy consisting of 30% gadolinium in magnesium. The master alloy is a semi-finished product. It is produced for use as a additive by the metals industry. It can be produced in various shapes. For example: ingot, waffle plate, rod in coils, etc.

The Master alloys are used worldwide. Invariably they are found in factory where metal is melted, alloyed with various elements and then cast into different shapes. This can be aluminium,magnesium, iron, steel and so on.

There are several reasons for adding master alloys to a melt. One of the main reason is composition adjustment, such as. changing the composition of the liquid metal to achieve the desired chemical specification.

The other important application is structure control - influencing the micro-structure of a metal during the casting and solidification process in order to change its properties. This properties include mechanical strength, ductility, electrical conductivity, surface appearance and corrosion resistance. The master alloy is also referred to as "hardener", "grain refiner" or "modifier" depending on its application.
