Tungsten Copper Electrodes

WCu alloy electrodes combining tungsten's hardness and high melting point with copper's conductivity — outstanding arc erosion resistance, anti-adhesion and heat dissipation for EDM, resistance welding and high-voltage discharge.

Materials: Tungsten copper (WCu), copper content 6–90%
Features: Higher erosion speed and lower wear than copper/graphite, accurate shape retention, customizable copper content 6–90%, small-batch multi-specification supply
Application: EDM electrodes for hardened steel, tungsten carbide and superalloy molds; projection and butt resistance welding electrodes; high-voltage vacuum discharge tube electrodes.

FAQ

Frequently Asked Questions

What materials and process are used for Tungsten Copper Electrodes?

Tungsten Copper Electrodes is made from Tungsten copper (WCu), copper content 6–90% and is formed by MIM/PM (metal injection molding / powder metallurgy) near-net-shape and sintered to a relative density of ≥ 98%, which keeps mechanical properties close to wrought material.

What are the key specifications of Tungsten Copper Electrodes?

Typical specifications: Material: WCu (tungsten copper); Copper Content: 6–90 wt% (customizable); Process: Isostatic pressing + sintered W skeleton + Cu infiltration; die pressing / extrusion / injection molding. The full parameter list is in the specifications table on this page; custom requirements can be discussed against your drawing.

What is the MOQ and lead time for Tungsten Copper Electrodes?

MOQ is 1000 pcs. Mold lead time is about 20 days (mold fee typically RMB 20–40k depending on part geometry), and production lead time is about 7 days once the mold is validated; secondary processing adds 3–5 days.
