(1) Taking a metal as the matrix, its content is generally greater than or equal to 50%, such as aluminum, copper, iron, etc.
(2) Generally, the elemental substance to be added is easy to burn, high melting point, high density and easy segregation, etc., which should not be added directly.
(3) The master alloy is an additive type of functional alloy material, unlike the cast aluminum alloy, deformation aluminum alloy, copper alloy, steel and other directly used in the production of castings.
Intermediate alloy compared with plans to join the elemental, generally have lower melting point, the dissolution rate of faster, more stable recovery efficiency and stronger ability to improve the performance of alloy, as a result, the intermediate alloy can be used in the alloy elements in the process of producing accurate and add adjustment, refine the grain size, modification treatment, purification processing, deoxidation desulphurization processing, solid solution hardening, etc., In aluminum and aluminum alloy, copper alloy, steel and other industries have a wide range of applications.
