What is master alloy?


It is a special alloy that is made by alloying certain monomers so that they can be easily added to the alloy to solve the problems of burnout, high melting point alloys that are not easy to be melted into, and at the same time have little effect on the raw materials, called intermediate alloys. For example, the alloy formed by mixing copper and A00 aluminium 1:1 and then dissolving them is relatively easy to mix into zinc water.

Master alloy is a metal as a substrate, will be one or several kinds of monomers added to solve the monomers are easy to burn, high melting point is not easy to melt, high density and easy to segregation and other problems or used to improve the performance of the alloy special alloy, is a kind of additive functional materials.


Steel, cast iron, high-temperature alloys, titanium alloys, magnetic alloys, aluminium alloys and non-ferrous metal materials such as smelting required for a variety of base alloys and additives. It cannot be used directly as a metal material. Master alloys are composite alloys consisting of more than two elements, except for mass-produced iron alloys. Intermediate alloy has complex composition and many varieties, which are designed according to the composition and special requirements of the smelted metal materials. Its classification can be divided into iron-based alloys, nickel-based alloys, aluminium-based alloys and so on according to the composition of the matrix, can also be classified according to the main elements of the alloy, but often called special alloys, in order to differentiate from mass-produced ferroalloys, such as silicon special alloys, calcium special alloys, boron special alloys, chromium special alloys, and so on; also according to the use of the composite alloying agent known as compound deoxidants, composite refining agents, composite additives (refining agent with the alloying agent), master alloy for vacuum smelting, inoculant, spheroidising agent, creeping agent, grain refining agent, denaturing agent, and so on.
