Copper alloys

Definition

Copper alloys are materials made by combining copper with one or more other elements to enhance specific properties such as strength, corrosion resistance, and conductivity. In the context of structural materials for fusion reactors, these alloys are significant due to their ability to withstand high temperatures and mechanical stress while maintaining effective thermal and electrical conductivity, making them suitable for components like heat exchangers and superconducting magnets.
