Tellurium Copper

Overview

Tellurium copper is a copper-based alloy primarily alloyed with tellurium and phosphorus. It fills the gap for high-conductivity copper alloys in precision machining, addressing the poor machinability of traditional copper and high cost of silver-copper alloys. Its core value lies in simultaneously offering high electrical/thermal conductivity, superior machinability, and corrosion resistance, making it ideal for precision industrial components.
