$0.00

Alloy 101 Copper Coil is an oxygen-free electronic (OFE) copper with a minimum copper content of 99.99%. Designed for high-performance electrical and electronic applications, it offers superior conductivity and excellent ductility. The coil format supports precision slitting, forming, and stamping operations. C101 is commonly specified where maximum electrical efficiency and material purity are critical. It is suitable for vacuum, high-temperature, and sensitive electronic environments.

Electrical: Vacuum components, high-conductivity conductors, RF components, bus bars, and power distribution systems.
Plumbing & HVAC: High-purity gas lines, specialty cooling systems, corrosion-resistant fittings, and heat exchanger components requiring ultra-clean copper.
Automotive: EV battery modules, high-performance connectors, and conductive systems in advanced electrical architectures.

A101 Copper Coil FAQs

Alloy 101 (OFE copper) contains a minimum of 99.99% copper and has extremely low oxygen content. Standard ETP copper (110) contains slightly lower purity and residual oxygen. Alloy 101 is specified when superior electrical conductivity and material purity are critical, particularly in sensitive electronic and vacuum environments.

Alloy 101 offers excellent ductility and performs well in forming, bending, and stamping operations. The coil format allows for efficient processing in precision manufacturing environments.
