How direct integration with Jiangxi’s primary tungsten reserves and modernized Sinter-HIP processing yields unmatched cost, volume, and quality predictability.
Located in Nanchang, Jiangxi—the epicenter of global tungsten ore refining. We process 100% virgin ammonium paratungstate (APT) powder without relying on scrap tungsten recycle residues, safeguarding your parts against trace contaminants.
Standard vacuum sintering leaves microscopic voids (A02-B02 porosity). Our factory applies 100-bar argon overpressure during the liquid-phase sintering plateau, collapsing internal micro-cavities to attain 99.98% theoretical density.
Equipped with AgieCharmilles wire EDM units, high-speed centerless grinding rigs, and surface lapping systems capable of delivering mirror surface finishes (Ra 0.05 μm) and h6 cylindrical tolerances directly from CAD models.
Meeting Western quality assurance protocols, supply chain audit standards, and regional manufacturing compliances across North America, Europe, and Asia-Pacific.
Global procurement teams must adhere to Section 1502 of the Dodd-Frank Act. Every metric ton of tungsten feedstock sourced by our facility is accompanied by Responsible Minerals Initiative (RMI) documentation, verifying supply chain traceability from certified, conflict-free smelters.
Our non-magnetic nickel-based alloys and cemented carbide grades undergo strict SVHC (Substances of Very High Concern) screening. Full RoHS laboratory test reports and REACH registration filings ensure frictionless import clearance into the EU and US jurisdictions.

Anticipating the technological shifts reshaping cemented carbide component fabrication over the next decade.
By refining WC grain size below 0.2 μm and incorporating secondary grain growth inhibitors (VC, Cr₃C₂), modern hardmetals break the inverse relationship between hardness and fracture toughness, producing cutters capable of dry-machining hardened steels up to 65 HRC.
Escalating regulatory scrutiny over cobalt handling has accelerated factory R&D into complex multi-element HEA (High Entropy Alloy) and Fe-Ni-Co-Cr binder matrices, delivering equal toughness with lower supply chain vulnerability and enhanced biocompatibility.
Direct Binder Jetting (BAM) of cemented carbide powders allows the creation of conformal cooling channels inside heavy-duty milling cutters and complex draw dies, reducing post-sinter grinding requirements by over 40%.
In-depth answers addressing metallurgical selection, order handling, custom tooling tolerances, and global freight workflows.
The primary determining factor is the dynamic impact ratio of your working condition. If the tool experiences pure sliding abrasion without shock (e.g., fine cast iron turning, wire drawing), YG6 provides maximum hardness (90.5 HRA). If the part withstands intermittent percussive shocks (e.g., tube scarfing, rock boring), YG8 is required. For severe punch stamping and cold extrusion dies, YG15 or YG20 (with 15-20% binder) is mandatory to prevent brittle fracture.
Standard vacuum sintering relies solely on capillary action of the liquid binder phase at 1400°C, frequently leaving sub-surface voids that act as stress concentrators during heavy mechanical loading. Sinter-HIP applies 60 to 100 bar of pressurized argon gas during the final sintering stage, physically collapsing residual pores. This elevates the Transverse Rupture Strength (TRS) by 25-35% and guarantees zero internal porosity for EDM die sinking.
Yes. By replacing cobalt with high-purity nickel binders modified with trace chromium additions, our metallurgical lab controls the austenitic phase stability, keeping magnetic permeability μ below 1.005. These components operate adjacent to high-sensitivity magnetometers in directional MWD drill collars without creating signal distortion.
For precision round rods, our centerless grinding lines routinely deliver ISO h6 diametrical tolerances with circular runout < 0.002 mm. For carbide plates and blocks, our CNC surface grinders achieve thickness tolerances within ±0.005 mm with parallelism and flatness < 0.003 mm across a 200 mm span, prepared with surface finishes down to Ra 0.1 μm or mirror finish Ra 0.05 μm.
Our technical team reviews drawings and delivers manufacturability feedback and price quotations within 8 business hours.
