CW009A Copper

CW009A is an ultra-high-purity, certified oxygen-free copper developed specifically for demanding electronic and electrical applications. Manufactured from pure cathode copper and cast under a protective gas atmosphere, this grade achieves an impressive minimum copper content of 99.99% and delivers electrical conductivity of at least 101.5% IACS. To guarantee resistance to hydrogen embrittlement, the oxygen content is strictly limited to no more than 5 ppm, while other individual impurities are capped at 25 ppm.

This alloy offers an exceptional combination of outstanding thermal and electrical conductivity, excellent formability, and superior weldability and joining performance. Thanks to its stable oxide film and consistent material properties, CW009A is the preferred choice in sectors where reliability and purity are non-negotiable, including electrical engineering, high-vacuum systems, and advanced manufacturing environments.

Key Advantages of CW009A Copper:

• Ultra-high purity composition
• Exceptional electrical conductivity
• Superior formability and workability
• Complete resistance to hydrogen embrittlement
• Excellent performance in welding and joining processes

Common Applications of CW009A Include:

CW009A is widely used in critical applications such as vacuum capacitors and circuit breakers, precision gaskets for vacuum equipment, magnetrons, semiconductor mounting bases, anodes, sensitive electronic components, rotor conductors in large generators and motors, and cryogenic electrical systems.
