Tungsten carbide parts
Custom Tungsten Carbide Components: Precision Engineered Solutions Tailored by Drawing
As a professional hardware parts manufacturer specializing in hard material machining, we excel in custom tungsten carbide (WC) components—leveraging the unique properties of cemented tungsten carbide to deliver high-wear, high-strength parts for extreme industrial applications. Our core capability lies in drawing-based customization (accepting 2D formats: DWG/DXF/PDF with GD&T; 3D formats: STEP/IGES/STL), enabling us to tailor every component to your exact specifications: material grade (cobalt-bonded WC, nickel-bonded WC), dimensional precision (tolerance grade IT5–IT7), surface finish (Ra ≤0.1μm), and functional requirements (impact resistance, corrosion resistance).
All our tungsten carbide components comply with global standards (ISO 513 for cutting tools, ISO 3325 for carbide plates, ASTM B777 for tungsten carbide materials) and are optimized for scenarios where traditional metals (steel, aluminum) or ceramics fail—thanks to WC’s inherent advantages: Mohs hardness 8.5–9 (second only to diamond), compressive strength up to 6000 MPa, wear resistance 5–10× higher than high-speed steel (HSS), and thermal stability up to 1200°C (in inert atmospheres).
1. Tungsten Carbide Material Fundamentals & Custom Grading
Tungsten carbide components are “cemented” composites—typically consisting of tungsten carbide (WC) particles bonded by a metallic binder (most commonly cobalt, Co; occasionally nickel, Ni, for corrosion resistance). Our material selection is tailored to your application, with custom grades defined by binder content, WC particle size, and additive elements.
Key Custom Material Grades
Material Advantages for Custom Components
- Ultra-High Wear Resistance: Wear rate ≤0.001mm/1000 cycles (vs. 0.005mm/1000 cycles for HSS)—ideal for high-volume production tools.
- High Temperature Stability: Maintains 80% hardness at 800°C—suitable for hot-forming or high-heat machining.
- Dimensional Stability: Low thermal expansion coefficient (4.5×10⁻⁶/°C)—ensures precision even in temperature-fluctuating environments.
- Custom Additives: We integrate trace elements (titanium carbide, TiC; tantalum carbide, TaC) to enhance specific properties—e.g., TiC for improved oxidation resistance, TaC for high-temperature strength.
2. Custom Tungsten Carbide Component Types
We specialize in manufacturing a full range of tungsten carbide parts, all customizable by your drawings. Below are our most in-demand product categories, with focus on customization dimensions and application-specific designs.
2.1 Tungsten Carbide Cutting Tools & Inserts
Cemented carbide is the gold standard for cutting tools—our custom inserts and blades are engineered for machining metals (steel, aluminum, titanium) and composites.

3. Our “Drawing-Based Customization” Process for Tungsten Carbide
Tungsten carbide’s extreme hardness (HRA 85–92) requires specialized machining equipment (diamond tools, EDM) and expertise. Our workflow ensures your drawings are translated into high-precision, defect-free components:
Step 1: Drawing Submission & Engineering Review
- Acceptable Formats: 2D (DWG/DXF/PDF with dimensional annotations, GD&T symbols, and surface finish specs) | 3D (STEP/IGES/STL for complex geometries).
- Engineering Consultation:
- Material Grading: Recommend WC grade (e.g., 6% Co for cutting tools, 15% Co for impact parts) based on your application.
- DFM (Design for Manufacturability) Optimization:
- Adjust wall thickness (minimum ≥1mm for WC to avoid sintering cracks).
- Modify complex features (e.g., deep holes ≥5× diameter) for diamond machining feasibility.
- Add fillets (radius ≥0.2mm) to reduce stress concentrations in high-impact parts.
- Quote Delivery: Technical quote (material cost, machining time, lead time) + material selection report within 24 hours.
Step 2: WC Powder Mixing & Compaction
- Custom Powder Blending: Mix WC powder with binder (Co/Ni) and additives (TiC/TaC) per your grade requirements—ensures uniform particle distribution (critical for sintering).
- Compaction: Use isostatic pressing (200–300 MPa) to form “green bodies” (pre-sintered parts) with dimensional tolerance ±0.5mm—matches your drawing’s net shape to minimize machining.
Step 3: Sintering
- Controlled Atmosphere Sintering: Heat green bodies to 1400–1500°C in vacuum or argon atmosphere (8–12 hours)—achieves ≥99.5% theoretical density (prevents porosity in high-pressure parts).
- Shrinkage Control: Precisely calculate shrinkage (15–20% for WC) to ensure final dimensions align with your drawing.
Step 4: Precision Machining
- Diamond-Tool Machining:
- CNC Diamond Grinding: For flatness (≤0.001mm/m), parallelism (≤0.002mm), and surface finish (Ra ≤0.1μm)—used for cutting tool inserts and precision seals.
- Wire EDM: For complex shapes (e.g., custom die cavities, micro-slots) with tolerance ±0.005mm—no mechanical stress (avoids cracking in brittle WC).
- Laser Micromachining: For micro-features (holes ≤0.1mm, grooves ≤0.05mm)—ideal for medical or semiconductor parts.
Step 5: Quality Inspection & Post-Processing
- Dimensional Testing:
- CMM (Coordinate Measuring Machine, accuracy ±0.0005mm): Verifies all dimensions against your drawing.
- Optical Profilometer: Measures surface roughness (Ra) and flatness.
- Material Testing:
- Hardness Test: Rockwell A (HRA) or Vickers (HV) tester—confirms grade compliance (e.g., HRA 90 for 6% Co WC).
- TRS Test (Transverse Rupture Strength): Ensures mechanical strength meets your application’s load requirements.
- Porosity Test: Ultrasonic inspection (UT) to confirm ≤0.5% porosity (critical for pressure-bearing parts).
- Post-Processing:
- Coating Application (TiAlN, diamond): Automated PVD/CVD coating lines for uniform thickness (2–10μm).
- Deburring: Laser or diamond-tool deburring—removes micro-burrs (≤0.01mm) for precision assembly.
Step 6: Delivery & After-Sales Support
- Packaging: Anti-rust oil + vacuum-sealed bags + foam-lined boxes (prevents chipping during shipping—critical for brittle WC parts).
- Documentation: CoC (Certificate of Conformance), MTR (Material Test Report), and inspection data (CMM results, hardness test records).
- Warranty: 12-month warranty—free replacement if parts fail due to manufacturing defects; technical support for installation and maintenance.
