Master Alloy Copper based CuCr10 Copper Chromium

Benefits of Master Alloys and Alloying Additives

A master alloy is a pre-alloyed concentrate or mixture of alloying elements. They are used to add all the major alloying elements in one form to the base metal. For example, a addition of 30% yttrium - 70% magnesium composition master alloy to produce Mg-Y30 alloy.

Master alloys are essential for adding small amounts of compounds with large melting point differentials. This is because adding a virgin metal to a melt can be inefficient in terms of energy and metal yield. For example, a small addition of pure copper (1083°C melting point) to a large mass of aluminum (660°C melting point) would require heating all the aluminum above 1083°C. A 50-50 master alloy of copper and aluminum eliminates unnecessary heating of the aluminum, allowing the correct percentage of this alloy to be added to the bulk of aluminum at a much lower temperature.

Master alloys are also the most effective method of introducing controlled levels of rare earth metals to more complex alloy systems. They help to control oxygen content within the alloy, stabilizing metals that would normally oxidize in the atmosphere
