Macro Industrial Landscape
The Global Strategic Imperative for Cemented Carbide
From modern aerospace engine profiling to subterranean energy extraction, tungsten carbide (WC-Co/Ni) is the backbone of high-stress modern manufacturing.
Supply Chain Resilience
Tungsten supply lines require strict traceability. Operating directly from Jiangxi, the global tungsten epicentre, our facilities secure virgin ammonium paratungstate (APT) feedstock, isolating tier-1 global procurement networks from speculative raw-material price surges.
Micron-to-Nano Grain Metallics
Next-generation CNC processing demands submicron and nano-grain cemented carbide matrices (≤0.4μm). By refining the WC grain boundary distribution, our metallurgical labs minimize micro-chipping while keeping compressive yield strength above 4,200 MPa.
Sinter-HIP Porosity Elimination
Atmospheric sintering fails when internal voids trigger structural failure in high-impact tooling. Our computerized 100-bar Sinter-HIP autoclaves dissolve micro-pores, ensuring density consistency approaching 100% theoretical limits (14.5–15.0 g/cm³).

Comprehensive Cemented Carbide Selection Guide
Balancing hardness (wear resistance) against transverse rupture strength (impact tolerance) for critical engineering procurement.
| ISO/Industry Grade | Binder Fraction (%) | Specific Density (g/cm³) | Hardness Rating (HRA) | Transverse Rupture (TRS, MPa) | Typical Wear Application |
|---|---|---|---|---|---|
| YG6 / K10–K20 | 6.0% Co | 14.85 – 15.00 | 90.5 – 91.5 | ≥ 1,900 | Chilled cast iron finishing, non-ferrous profiling, wire drawing dies. |
| YG8 / K20–K30 | 8.0% Co | 14.60 – 14.80 | 89.5 – 90.5 | ≥ 2,200 | Mining drill bits, percussive tamping tines, stone cutting, wood scarfing. |
| YG15 / K40 | 15.0% Co | 13.90 – 14.15 | 87.0 – 88.0 | ≥ 2,800 | Cold heading punches, high-impact metal stamping, deep-drawing dies. |
| YG20 / High-Impact | 20.0% Co | 13.40 – 13.65 | 85.0 – 86.5 | ≥ 3,200 | Heavy blanking dies, cold punching thick alloys, severe shock tooling. |
| Ni-Bond (Non-Magnetic) | 6.0–10.0% Ni | 14.40 – 14.85 | 88.0 – 90.0 | ≥ 2,100 | Water meter shafts, downhole MWD/LWD sleeves, corrosion-prone chemical seals. |
Field Application Engineering
Engineered Solutions for Extreme Field Scenarios
Custom formulations tailored to high-wear, high-impact, and chemically aggressive operational environments.
Automated Steel Tube Scarfing
Our heavy-duty scarfing inserts (SPUB63, SPUB86, SNMX series) operate continuously on automated welding lines. Multi-layer CVD coatings resist thermal shock, stripping internal and external weld beads at high line speeds without edge chipping.
Subsea Drilling & Flow Control
Nickel-bonded non-magnetic components eliminate interference with downhole directional telemetry sensors while withstanding abrasive slurries and sour gas (H2S), extending field service life across downhole tools.
Semiconductor & Micro-Machining
Ultrafine-grain rods ground to h6 diameter tolerance provide runouts under ±0.002 mm. These stable blanks serve as precision bases for solid carbide micro-drills (≤Ø0.3 mm) and routers used in PCB and package carrier machining.
Compliance & Assurance
Global Standards Compliance & Quality Infrastructure
Traceable manufacturing processes certified to international industrial and environmental standards.
Strict Conflict-Free Minerals
We source raw tungsten exclusively from compliant, responsible smelters following OECD Due Diligence Guidance and the Responsible Minerals Initiative (RMI), meeting RMAP requirements for North American and European supply chains.
Traceable Metallography Inspection
Every batch undergoes metallographic checks, magnetic saturation testing, and coercivity screening. Certified Mill Test Reports (MTR) including density, hardness, and grain size analysis are provided with every production run.
Cross-Border Logistics Integration
Standardized export packaging features vacuum-sealed, anti-corrosive wrapping in reinforced wooden cases. We coordinate DDP and CIF shipments via air and ocean freight to hubs across North America, Europe, Australia, and ASEAN.
Technology Roadmap
Advancements in Powder Metallurgy & Tool Coatings
Continuous investment in sintering science and thin-film tribology to extend component service life.
Binder Phase Optimization
We are advancing alternative iron-nickel-chromium binders (Fe-Ni-Cr) to replace cobalt in corrosive chemical environments, reducing binder leaching in acidic and alkaline working fluids.
Plasma PVD & Multilayer CVD Coatings
In-house High Power Impulse Magnetron Sputtering (HiPIMS) produces dense AlTiN, AlCrN, and diamond (CVD) thin films, extending tool life in hard turning applications up to 65 HRC.
Direct Powder 3D Binder Jetting
Developing near-net additive manufacturing for complex tooling geometries, cooling channels, and prototypes without expensive hard tooling or extensive post-sinter grinding.
Technical Inquiries
Frequently Asked Questions by Industrial Buyers
Clear, direct answers from our metallurgical engineering and international supply team.
Can you manufacture custom tungsten carbide components directly from technical drawings?
Yes. Custom carbide parts are our core business. We support 2D prints (DWG, DXF, PDF) and 3D models (STEP, IGES). Our engineering team reviews tolerances, surface finishes, and operating parameters to recommend optimal grades and powder formulations.
What cemented carbide grades and formulations do you supply?
We supply standard WC-Co grades from YG6 to YG20, ultrafine sub-micron rod blanks for solid end mills, and nickel-bonded non-magnetic grades. Low-cobalt grades maximize wear life, while higher cobalt fractions provide impact toughness.
What distinguishes non-magnetic tungsten carbide from standard grades?
Standard cemented carbide uses a ferromagnetic cobalt binder. Non-magnetic carbide utilizes a specialized nickel or composite binder phase, ensuring low magnetic permeability (µr ≤ 1.05) for water meters, MWD/LWD downhole components, and magnetic stamping dies.
What is your engineering response and quote turnaround timeframe?
Our sales and applications engineering teams reply within 8 hours. We provide initial manufacturability assessments (DFM), grade options, and cost estimates promptly.
Which global industrial regions do you regularly export to?
We export to over 20 countries worldwide, including the United States, Germany, Canada, Mexico, Australia, Italy, and South Korea, offering full documentation for smooth customs clearance.
How does Sinter-HIP technology prevent internal micro-porosity?
During the terminal sintering cycle, the furnace applies up to 100 bar of high-purity argon gas at 1,450°C. This combines liquid-phase sintering with isostatic pressing to eliminate micro-voids, elevating density and rupture strength.
