High Purity Refined Copper Billets
High purity refined copper billets (99.99% Cu) are cylindrical semi-finished products used primarily for extrusion into rods and wires. They fall under HTS 7403.13.00.00 as unwrought refined copper in billet form, distinct from castings or other shapes. These billets are produced by continuous casting and are essential for electrical wiring and conductors.
Electrolytic Tough Pitch Copper Billets
Electrolytic tough pitch (ETP) copper billets are refined copper (99.9% Cu with controlled oxygen) cast into billet form for wire rod production. Classified under HTS 7403.13.00.00 as unwrought refined copper billets, they are key for high-conductivity applications like power cables. Produced via electrolytic refining for optimal electrical properties.
Oxygen-Free High Conductivity Copper Billets
Oxygen-free high conductivity (OFHC) copper billets feature ultra-low oxygen content (<10 ppm) for superior electrical performance in billets used for magnet wire. They qualify under HTS 7403.13.00.00 as unwrought refined copper billets. Ideal for semiconductors and RF applications due to high purity.
Continuous Cast Copper Billets for Rod Extrusion
Continuous cast refined copper billets, typically 200-300mm diameter, are designed for hot extrusion into copper rods for subsequent drawing into wire. HTS 7403.13.00.00 covers these unwrought refined copper billets. Produced via horizontal continuous casting for uniform microstructure.
