Introduction
A master alloy is a combination of base metals such as copper, aluminum, or nickel, and one or two other elements of comparatively higher percentage. It is a semi-finished product that is manufactured for use as a raw material in the metal industry. Master alloys can be produced in many shapes.
The two main applications of master alloys are composition adjustment and structure control. These alloys are preferred over pure metals as they are more profitable, and save production time and energy as they melt faster at lower temperatures.
Copper-cadmium 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 base metal and the element are equal in composition. The following datasheet will provide more details about the copper-cadmium master alloy.
