Copper-Based Master Alloys


Deoxidants remove oxygen from copper baths to produce a copper bath that is free of dissolved oxygen.

Alloying Agents
Used as an alloying agent in copper-tin alloys and in high performance electrical conductive alloys, Phosphorus-Copper increases their strength, hardness and elasticity while reducing creep and grain growth.

Wetting Agents
When added to brazing rods, Phosphorus-Copper lowers melting temperatures and improves wetting characteristics, resulting in a cleaner, stronger brazed joint.

Several Milward copper alloys are used to change the composition of metal alloys that require heat treatment to improve strength and wear resistance. These include Iron-Copper, Silicon-Copper, Nickel-Copper, Magnesium-Copper, and Manganese-Copper.
