Oxygen Free Copper Tube for Electrical & Electronic Application
Oxygen Free Copper Tube is widely used in electrical and electronic systems that require high conductivity, efficient heat dissipation, and material purity. Manufactured from high-purity oxygen-free copper, it provides stable electrical performance and excellent thermal transfer characteristics for demanding applications. To accommodate different design and manufacturing requirements, the tubes are available in a broad range of diameters, wall thicknesses, and supply forms, including straight lengths and coils.
