China Non Magnetic Carbide Factory & Factories

Non-magnetic carbide is characterized by a relative magnetic permeability (μr) close to unity, typically μr ≤ 1.005, with virtually zero magnetic remanence or coercivity. In our facility, magnetic susceptibility is tested using calibrated fluxgate magnetometers and Gouy balance setups, ensuring total non-interference in sensitive electronic or geological survey environments.

Yes. Non-magnetic carbide grades with nickel or nickel-chromium binders are fully conductive and cut efficiently via electrical discharge machining (EDM). However, because nickel binders interact differently with dielectric fluids, we recommend anti-corrosion EDM dielectric fluid and prompt drying to eliminate any risk of minor surface oxidation. Diamond grinding wheels (resin or vitrified bond) are used for final precision finishes down to Ra 0.05.

Historically, replacing cobalt with nickel resulted in a slight reduction in transverse rupture strength (TRS). However, using advanced Sinter-HIP processing and sub-micron WC powder formulation, our modern non-magnetic alloys achieve hardness ratings of 88 to 92.5 HRA and TRS values exceeding 2200 MPa—matching or exceeding conventional grades like YG8 and YG15 across most wear and impact applications.

For standard stocked preforms, rods, and inserts, there is no minimum order quantity (MOQ: 1 piece). For custom geometries requiring tailored pressing dies, our standard turnaround is 7–10 working days for prototyping and tooling samples, and 15–20 working days for volume batch sintering and final ground dimensions.

We operate strictly under ISO 9001:2015 quality management procedures. Every production batch undergoes strict metallographic microstructure checks, density validation, and CMM dimension audits. We routinely execute bilateral Non-Disclosure Agreements (NDAs) with global clients to ensure proprietary part profiles and patented tooling designs are safeguarded.
