Copper C101 | CU OFE

Engineers and manufacturers prefer this premium-grade copper.

Exceptional Electrical Conductivity

C101 copper achieves up to 101 % IACS conductivity, minimizing resistive losses in power and signal systems. This results in higher efficiency and lower heat generation in critical assemblies.

Superior Thermal Management

With thermal conductivity near 390 W/m·K, this material dissipates heat rapidly, making it perfect for heat exchangers, high-power electronics, and precision cooling systems.

High Purity and Vacuum Compatibility

Its ultra-low oxygen and impurity content make C101 ideal for vacuum chambers and cleanroom environments where contamination or outgassing must be minimized.

Excellent Machinability and Formability

Despite its softness, C101 can be machined to ultra-tight tolerances with proper technique. It can also be bent, formed, or joined without cracking, allowing versatile design freedom.

Long-Term Durability and Corrosion Resistance

C101 resists oxidation and chemical attack better than many standard coppers, especially when coated or plated. Its stability ensures consistent performance over time and under load.
