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.
Master alloys are mostly used in the metal industry. Their chief applications are composition adjustment and structure control. These alloys are favored over pure metals as they are more economical, and save production time and energy as they melt faster in lower temperatures.
Copper-zinc master alloy has the main characteristics of copper, which is a soft, conductive, non-ferrous metal. Copper is also resistant to corrosion and is ductile. In this case, the copper and zinc can be combined in various compositions. The following datasheet will provide more details about the copper-zinc master alloy.
