Operating from Nanchang, Jiangxi Province, Jiangxi Zhongfu Cemented Carbide Co., Ltd. sits at the absolute center of global tungsten mineral reserves. This geographic adjacency yields uncompromised chemical purity, primary ammonium paratungstate (APT) security, and unparalleled pricing agility for global OEM partners.
100% Virgin Powder Sourcing
We reject black-market scrap recycling for our structural and die plate lines. By utilizing strictly virgin tungsten carbide (WC) micro-powders blended with metallurgical cobalt and nickel binders, we eliminate random secondary grain growths, chemical contamination, and micro-inclusions that cause spontaneous failure during wire electrical discharge machining (WEDM).
Overpressure Sinter-HIP Technology
All Zhongfu carbide plates undergo secondary high-pressure consolidation inside advanced Sinter-HIP autoclaves operating at 1,450°C under argon gas pressures reaching 10 MPa (100 bar). This process closes microscopic shrinkage voids and collapses micro-pores to Grade A00/B00 porosity ratings, enhancing transverse rupture strength by over 25%.
Total Cost of Ownership (TCO) Advantage
Eliminating third-party trading intermediaries allows us to pass raw supply advantages directly to high-volume manufacturing entities. Our lean manufacturing cells, in-house die cavity electrical discharge cutting, and multi-axis CNC surface grinding achieve factory-direct savings while exceeding European and North American tooling lifespans.
Solving Global OEM Wear Challenges: Hardness vs. Fracture Toughness
International tool makers, stamping plant procurement engineers, and precision component designers frequently encounter trade-offs when specifying carbide grades. A plate that is too hard will chip under shock impact, while a binder-rich ductile plate wears out rapidly under abrasive friction. Zhongfu solves this dynamic through granular metallurgy control.
Eliminating EDM Cracking
When wire-cutting thick block stock (e.g., 100×100×60 mm), conventional cemented carbide often experiences spontaneous micro-cracking due to residual tensile stress. Zhongfu implements a proprietary multi-stage thermal stress-relief annealing cycle after Sinter-HIP consolidation, lowering internal structural stress to < 50 MPa. Toolmakers can cut complex progressive punch cavities without premature cracking.
Controlling Sub-Surface Porosity
Mirror-finish lamination stamping dies and semiconductor lead-frame trim blocks require sub-micron diamond polishing without pit mark breakouts. Our strict control of carbon balance eliminates eta-phase (W3Co3C carbon deficiency) and free graphite rosettes. This yields mirror surface finishes down to Ra 0.05 µm without orange-peel imperfections or microscopic pitting.
Near-Net Shape Powder Compaction
Diamond grinding carbide is a costly bottleneck in precision fabrication. Zhongfu utilizes computerized high-tonnage hydraulic and CNC multi-axis automatic presses equipped with custom-milled carbide compaction dies. We produce near-net flat plates with standard grinding allowances of just 0.3 mm to 0.8 mm, cutting finish-machining cycle times by up to 40%.

Tailored Performance Across Demanding Operating Environments
Zhongfu carbide plates and wear blocks are deployed in critical heavy-industry manufacturing, high-speed automated stamping, downhole petroleum extraction, and continuous steel mill conditioning operations.
Automotive Stamping & Motor Lamination Dies
High-speed punching of silicon steel motor cores and ultra-high-strength steel (AHSS) structural automotive panels demands extreme edge retention. Our YG15 and YG20 plates deliver tens of millions of strokes between regrinds, drastically decreasing factory press downtime and edge burr defects.
Downhole MWD/LWD & Subsea Flow Control
Downhole measurement-while-drilling (MWD) logging suites require wear-resistant materials that do not interfere with magnetic compasses. Zhongfu non-magnetic nickel-bonded plates and flow trim rings exhibit relative magnetic permeability (µ) under 1.005, alongside resistance to severe H2S/CO2 sour gas corrosion.
Tube Scarfing & Continuous Heavy Milling
In welded ERW pipe production, removing red-hot continuous weld beads requires heavy-duty scarfing inserts such as SPUB63, SPUB86, and SNMX lines. Our specialized shock-resistant substrates resist thermal shock and mechanical gouging, outlasting conventional PVD-coated steel tools across continuous shifts.
Precision Dicing & Semiconductor Tooling
Fine-grain WC plates featuring sub-micron grain sizing (0.4–0.8 µm) allow EDM wire-cut toolmakers to create razor-sharp shearing blades, wire bonding anvil wear blocks, and IC encapsulation punch guides with zero edge chipping under high-frequency automated assembly cycles.

The tungsten carbide sector is transitioning rapidly from standard mechanical pressing to AI-controlled metallurgical compaction and environmentally responsible material lifecycle management.
Ultra-Fine & Nanocrystalline Grain Sizing
By incorporating advanced grain growth inhibitors (VC, Cr3C2, and TaC) during high-energy attritor milling, Zhongfu develops carbide plates with sub-0.5 µm uniform grain matrices. This produces plates with exceptional hardness (> 92 HRA) without compromising transverse rupture strength, ideal for micro-machining tools.
Digital Density Scanning & Smart Compaction
Variations in green part density cause uneven shrinkage during sintering, leading to warped plates. Our factory employs computer-monitored multi-stage hydraulic pressing that continuously monitors powder feed flow and compaction pressures, ensuring uniform green density throughout blocks up to 300×300 mm.
Sustainable Closed-Loop Recycling
In keeping with environmental goals, Zhongfu participates in circular zinc-recovery reclamation programs for clean scrap inserts, converting non-critical tooling into standardized industrial grade blanks while keeping primary virgin powder lines clean for aerospace and high-precision die applications.

Yes. Custom OEM parts are our core specialty. Simply provide your 2D (DWG/PDF) or 3D (STEP/IGES) files specifying dimensional tolerances, required ground finish, and operating conditions. Our engineers will recommend the optimal grade and supply near-net sintered or fully ground plates.
Standard unground Sinter-HIP blanks in YG6 through YG20 grades are produced within 10 to 14 working days. Custom pressed shapes, non-standard grades, or high-precision diamond surface-ground plates generally ship in 18 to 25 business days. Rapid air freight takes 4–6 days worldwide.
We use strict vacuum Sinter-HIP cycles followed by a computer-monitored secondary thermal annealing cycle to minimize residual internal stresses. Each EDM block is verified using ultrasonic flaw detection to ensure no internal voids or density gradients are present.
Our CNC surface grinders and precision double-disc lap grinding machines routinely hit thickness and flatness tolerances of ±0.005 mm (±0.0002"), parallelism within 0.005 mm, and surface finishes down to Ra 0.1 µm. Mirror polishing to Ra 0.05 µm is available upon request.
Cobalt-bound carbide is magnetic and susceptible to acidic chemical attack. If your application involves corrosive slurries, petrochemical environments, magnetic sensor components, or magnetic powder compaction dies, nickel-bonded carbide is required to prevent binder leaching.
For standard cross-sections, our MOQ is just 5 to 10 pieces for prototyping and first-article validation. For custom-tooled compaction dies, we evaluate requests based on total project scope, supporting pilot runs prior to high-volume commercial production.
