Copper tungsten ring used for electrode
This copper tungsten ring is a precision-engineered electrode component for electrical discharge machining (EDM), spark erosion, and resistance welding. The alloy, typically CuW50 (50% Cu / 50% W), CuW70, or CuW80, combines copper’s conductivity with tungsten’s arc resistance, making it ideal for high-precision tooling and mold applications. The rings are supplied as consumables for industries requiring repeatable performance in demanding machining environments.
The material’s high thermal conductivity and low thermal expansion minimise distortion during EDM, ensuring consistent surface finishes. Standard industry designations include ASTM B702, RWMA Class 10-12, and GB/T 8320-2003, which define the alloy’s mechanical and electrical properties. The rings are often custom-produced to buyer drawings, allowing for tailored dimensions and tolerances to fit specific machinery.
Primary buyers include tool and die manufacturers, aerospace component producers, and precision mold shops. These sectors rely on the rings’ ability to withstand high temperatures and electrical stress without degrading. The product is typically shipped in bulk, with packaging adapted to protect against oxidation and physical damage during transit. Importers should confirm the alloy grade and dimensional specifications to align with their machining requirements.

Sourcing Copper tungsten ring used for electrode from Shenzhen Wande Copper Alloy Co., Ltd - China Import Guide
Prior to ordering, confirm the alloy grade (e.g., CuW50, CuW70) and verify that it meets the RWMA or ASTM standards required for your machinery. Request the supplier’s technical datasheet to review thermal, electrical, and mechanical properties. For custom orders, provide detailed drawings and specifications to avoid mismatches in dimensions or tolerances.
Clarify the Incoterms (e.g., FOB Shenzhen) and lead times, as these impact shipping costs and delivery schedules. Bulk packaging is typical, but discuss options for protecting the rings from oxidation or damage during transit. Payment terms should be negotiated in advance, with TT or LC being common for international orders.
Conduct quality checks by inspecting the rings for surface defects and verifying dimensions with precision tools. For critical applications, arrange third-party testing for hardness, conductivity, and compliance with RWMA or ASTM standards. Request batch-specific test reports from the supplier to ensure consistency and traceability.
