Copper tungsten
Xiamen Huiyuan Import & Export Corp.Ltd supplies copper tungsten alloy (CuW75) composed of 75% tungsten and 25% copper, a material prized for its combination of thermal conductivity, arc resistance and wear resistance. This alloy is available in round bars and plates, making it suitable for electrical contacts, EDM electrodes and welding applications where high performance under thermal stress is required.
Copper tungsten alloys like CuW75 typically achieve a density of 16.5 to 17.5 g/cm³, with thermal conductivity around 180 to 200 W/m·K and electrical conductivity of 40 to 50% IACS. The material is often produced to standards such as ASTM B702 or ISO 13384, and can be machined to tight tolerances for precision components. Its high melting point (approximately 3400°C) and low thermal expansion make it ideal for extreme environments.
Industries such as aerospace, electronics and manufacturing rely on this alloy for components like circuit breaker contacts, resistance welding electrodes and heat sinks. Xiamen Huiyuan Import & Export Corp.Ltd provides export-grade packaging for international logistics, with buyers advised to confirm dimensions, surface finishes and certification compliance for their specific use.

Sourcing Copper Tungsten from Xiamen Huiyuan Import & Export Corp.Ltd - China Import Guide
Before ordering, verify the exact alloy composition (e.g., 75% W / 25% Cu) and confirm whether the material meets standards like ASTM B702 or ISO 13384. Request test certificates for thermal conductivity, electrical conductivity and hardness, as these properties directly impact performance in electrical and thermal applications.
Discuss logistics details such as the port of loading (e.g., Xiamen), Incoterms (FOB or CIF) and lead times, which can vary based on order size and production schedules. Packaging should be export-grade to protect the material during long-distance shipping, particularly for heavy alloys like copper tungsten.
Upon receipt, inspect the material for dimensional accuracy, surface defects and compliance with specified tolerances. Conduct non-destructive testing (e.g., ultrasound for internal defects) if required for critical applications. Ensure all documentation, including mill test certificates and packing lists, is provided to support quality control and customs clearance.
