 Master alloys can be divided into aluminum-based master alloys, copper-based master alloys, iron-based master alloys, magnesium-based master alloys, nickel-based master alloys, etc. according to different substrates.
Master alloys can be divided into alloying master alloys (additive master alloys), grain refinement master alloys, metamorphic master alloys, purification master alloys, deoxidation and desulfurization master alloys, etc. according to their uses.
Alloying master alloy
Alloying master alloys are also called additive master alloys, whose main function is to add certain elements to the melt. Compared with the melt matrix elements, these elements generally have the following characteristics:
(1) High melting point, such as adding Si, Fe, Cr, Cu, V and other elements to aluminum;
(2) Easily volatile and burning, such as adding elements such as Mg and Ca to aluminum;
(3) Poor wettability, such as adding B, C and other elements to aluminum;
(4) The density difference is large, and it is easy to segregate, such as adding Bi, Sn and other elements to aluminum.
If these elements are directly added to the melt in the form of simple substances, it is necessary to increase the adding temperature, prolong the smelting time, or increase the burning loss during the addition, and the actual yield is difficult to ensure, resulting in multiple adjustments of the ingredients in the furnace, which affects the product Productivity. Therefore, in order to reduce production costs and obtain a more accurate alloy composition, the above elements are generally added in the form of a master alloy. Commonly used alloying master alloys in industrial production are: Al-Si, Al-Fe, Al-Cr, Al-Cu, Al-Mn, Al-V, Al-Zr, Cu-Mg, Cu-Li, Cu -Ca etc.
