Edm copper wire
The product is an EDM copper wire supplied by Silver Gain Technology Co., Ltd., located in Foshan, Shunde, China. It is manufactured from Electrolytic Tough Pitch copper (Cu‑ETP, C11000) with a minimum purity of 99.9 %. The wire is offered in diameters between 0.10 mm and 0.33 mm, matching the range commonly required for precision spark erosion. The supplier states that the wire provides consistent electrical conductivity suitable for die‑sinking and mould machining.
Cu‑ETP wire of this grade typically meets IEC 60317 Class 1 specifications for conductivity and tensile strength, delivering around 58 MS/m and 210 MPa respectively. Standard industry practice applies a surface roughness of Ra ≤ 0.8 µm to ensure smooth feeding through EDM spindles. The supplier also mentions the use of Japanese‑grade drawing machinery, which helps achieve straightness and dimensional stability.
Typical applications include aerospace component machining, automotive mould production and high‑precision tool making, where the wire’s low wear rate improves tool life. Importers usually request bulk packaging in anti‑static reels of 500 m length, with the option to customise coil size on special order. Because the listing does not disclose minimum order quantity or lead time, buyers should confirm these details directly with the supplier. Payment terms and Incoterms are negotiated per transaction, so clarifying them before order placement is advisable.

Sourcing Edm copper wire from Silver Gain Technology Co., Ltd. - China Import Guide
Before placing an order, importers should obtain a recent mill test report that confirms the copper purity, diameter tolerance and surface roughness of the wire. Requesting a sample coil can help assess straightness and feeding behaviour in the buyer’s EDM spindle. It is also prudent to verify the supplier’s ability to meet any required certifications, such as IEC 60317, especially if the wire will be used in regulated aerospace projects.
The typical shipping method for bulk copper wire is containerised sea freight, with the supplier able to load reels onto a 20‑foot or 40‑foot container. As the listing does not state a fixed lead time, buyers must ask for the production schedule and expected dispatch date. Common Incoterms used in the industry are FOB Shanghai or CIF Ningbo; payment terms are usually a 30 % advance letter of credit followed by balance on sight.
Upon arrival, the buyer should arrange a visual inspection for coil integrity and a dimensional check using a calibrated micrometer to confirm diameter tolerance. Electrical conductivity can be verified with a four‑point probe test, and a certificate of conformity should accompany the shipment. If the buyer requires third‑party inspection, they can engage a recognised agency to perform pre‑shipment sampling and issue a report before customs clearance.
