· Er167Cu833

Er167Cu833 is a copper-erbium alloy containing approximately 16.7% erbium and 83.3% copper by composition, belonging to the family of rare-earth copper alloys. This material combines copper's excellent thermal and electrical conductivity with erbium's hardening and oxidation-resistance properties, making it relevant for high-performance applications requiring both electronic function and mechanical durability. The alloy is employed in specialized industrial sectors where conventional copper alloys cannot meet combined demands for thermal management, corrosion resistance, and strength.
