EJ EDM brass wire is supplied in CuZn37 and CuZn40 grades, containing approximately 60‑63 % copper and 37‑40 % zinc, and is engineered for electrical discharge machining applications. The wire delivers a tensile strength between 900 and 1,100 N per square millimetre and a conductance of 19‑24 % IACS, which ensures stable cutting performance across major WEDM machines. East Jin International, located in Seoul, South Korea, offers this wire with a straightness tolerance of 30 µm or less per metre and optional surface coatings on request.
In the EDM industry, typical wire diameters range from 0.1 to 0.3 mm, with a standard surface finish of 0.8 µm Ra to minimise friction during high‑speed cutting. The material is commonly supplied on spooled cardboard cores, each weighing about 1 kg, facilitating easy handling and automated feeding. Straightness and consistent elongation of 1‑2 % are standard quality parameters that help maintain dimensional accuracy in mould and die production.
Primary users include mould makers, tool‑and‑die manufacturers and aerospace component producers who require precise, repeatable cuts. The supplier’s listing does not disclose minimum order quantities, pricing or lead times, so those details should be confirmed directly. Importers should request the latest inspection report and verify that the wire meets the required EDM machine specifications before finalising a bulk purchase.

Confirm that the supplier can supply a current inspection certificate covering tensile strength, conductance and straightness, as these parameters directly affect EDM performance. Ask for a sample of the requested wire diameter and coating to test compatibility with your specific machine before committing to a larger order.
Discuss logistics early, specifying the preferred Incoterm such as FOB Shanghai or CIF Busan, and request an estimated production lead time based on your order volume. Because the supplier’s response metrics are not provided, establish a clear point of contact and agree on a timeline for order confirmation, production scheduling and shipment. Payment terms should be negotiated and documented, typically involving a deposit with balance payable against shipping documents.
Arrange for an independent quality audit at the factory or a pre‑shipment inspection to verify that the wire meets the declared straightness and tensile specifications. Ensure that the supplier can provide material safety data sheets and any required export documentation for brass products. Maintaining these checks will help minimise the risk of non‑conforming wire reaching the manufacturing floor.
