Introduction
A master alloy is a combination of base metals such as copper, aluminum, or nickel, and one or two other elements of relatively higher percentage. It is a semi-finished product that is primarily manufactured for use as a raw material. Master alloys can be produced in many shapes such as waffle plate, ingot, and rod in coils.
Master alloys are mainly used in the metal industry. Their two main applications are composition adjustment and structure control. These alloys are preferred over pure metals as they are more economical, and save production time and energy as they melt faster in lower temperatures.
Copper-boron master alloy has the features of copper, which is a soft, conductive, non-ferrous metal. Copper is also resistant to corrosion and is ductile. The following datasheet will provide more details about the copper-boron master alloy.
