Conductive Pieces for Wire EDM Machines

As a common consumable for Wire EDM machines, the quality of EDM conductive pieces significantly impacts machining efficiency.

Tungsten carbide, the core material of EDM conductive pieces for Wire EDM machines, offers the following advantages:

High Hardness and Wear Resistance: 

During Wire EDM machining, the wire electrode frequently rubs against the conductive block surface, effectively resisting wear and deformation, 

thereby preventing precision degradation from aperture enlargement or edge collapse.

High-Temperature Stability: 

Even at high discharge temperatures and high-frequency arc shock, tungsten carbide retains its red hardness and oxidation resistance, 

maintains stable shape and performance, and prevents thermal deformation that could affect machining accuracy.

Excellent Electrical and Thermal Conductivity: 

Conductivity ≥42% IACS ensures efficient current transfer to the wire electrode while rapidly dissipating heat, reducing localized overheating and electrode loss. 

And improving cutting efficiency.

Corrosion Resistance and Impact Toughness: 

Highly resistant to acid and alkali corrosion in the working fluid, its high density withstands high-voltage arc shocks without breaking, 

ensuring continuous processing stability.

Why choose our EDM conductive pieces?

We produce EDM Power Feed Contacts according to the original conductive pieces. (Charmilles, Sodick, Fanuc, Mitsubishi, Makino, etc.)

We only use high-quality tungsten carbide materials.

We partner with the latest grinding machines to ensure strict dimensional control.

We maintain a large inventory and keep stock levels in order to control costs.

Since the middle of the year 2025, the cost of tungsten carbide has increased 7-8 times.

Some customers may find the prices can't be acceptable, or the quality is not as good as before.
