Copper-Titanium (CuTi) Master Alloy

Topics Covered

Chemical Composition


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 metal industry. Master alloys can be produced in many shapes. They improve metallurgy processes by refining the final properties of different metals.

The two main applications of master alloys are structure control and composition adjustment. Master 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-titanium 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-titanium master alloy.
