Copper C110 (ETP)

Copper C110 is a commercially pure, oxygen-free copper grade (>99.9% Cu) widely used where electrical conductivity and thermal performance are critical. It is the standard choice for electrical wiring, busbars, transformers, and heat exchangers because of its excellent electrical and thermal transport properties combined with good workability. Engineers select C110 over lower-purity copper grades when oxygen contamination must be minimized to avoid brittleness in welded or cold-worked components, and over specialty alloys when the application does not require strength at elevated temperature or corrosion resistance beyond what pure copper naturally provides.
