Aluminum Master Alloy :
(1) Obtaining a metal material with a precise chemical composition and a uniform distribution. If the content of the metal component is less, the distribution of the added element in the material can be improved. For example, vanadium smelting Ti-6A1-4V alloy with vanadium-aluminum alloy.
(2) Adding chemical activity, low melting point, and volatile elements, such as boron, calcium, magnesium, or the like. To use of master alloy can reduce the burning of element during the addition to get stable alloy composition and a high element recovery efficiency.
(3) Add a high melting point metal. Master alloy such as tungsten, molybdenum, titanium, niobium, or chromium can lower melting temperature, shorten the melting time of the metal material, and lower smelting temperature.
(4) To use master alloy can add variety of elements at same time to complete refining and alloying. Simplify smelting operations and reduce refining time.
(5) To use pure master alloy can reduce the impurity content of the metal material. For example, the “VQ” grade master alloy is used for vacuum smelting.
(6) Reduce the production cost of metal products. Requirement for master alloy is that melting point is as low as possible, chemical composition is uniform, segregation is small; no visible non-metallic inclusions, gas content is low, impurity content must meet the requirements of smelted metal material, it is easily broken and stored in the air without deterioration.
