Product Overview
Our custom tungsten carbide rods are engineered for demanding industrial applications where standard materials fail. Manufactured using high-purity tungsten carbide (WC) and cobalt (Co) binders, these rods deliver exceptional hardness (88.8-94 HRA), wear resistance, and structural integrity-making them ideal for cutting tools, wear parts, and high-stress mechanical components.
Whether you need specific diameters, lengths, surface finishes, or alloy compositions, we provide tailored carbide rod solutions to meet exact specifications.
Key Features & Benefits
1. Ultra-High Hardness & Wear Resistance
Hardness: 88.8-94 HRA (superior to tool steel and most ceramics)
Exceptional abrasion resistance for extended service life in harsh environments
Ideal for cutting tools, mining drills, and wear-resistant components
2. Customizable Dimensions & Tolerances
Diameter range: 0.1mm – 45mm (±0.002mm precision)
Length options: Up to 1500mm (longer lengths available upon request)
Tolerance levels: Standard (±0.01mm) or high-precision (±0.002mm)
3. Multiple Material Grades for Specific Needs
| Grade | Cobalt Content | Grain Size (μm) | Best For |
|---|---|---|---|
| KU10 | 6% | 0.4 | Engraving tool and high mirror polished cutting tool |
| KU20 | 10% | 0.7 | Mining, drilling, good general performance |
| KR10Z | 10% | 0.6 | Mining, drilling, high-speed machining |
| KU209 | 9% | 0.2 | High-precision and high-mirror processing |
More options are available for different applications.
4. Superior Corrosion & Heat Resistance
Stable up to 1,000°C (1,832°F) without deformation
Resistant to acids, alkalis, and oxidation (ideal for chemical processing)
Low thermal expansion ensures dimensional stability
5. Machining & Surface Finish Options
Precision grinding: Mirror finish (Ra ≤ 0.05μm) for tight-tolerance applications
EDM/Wire-cutting compatible for complex geometries
Coating-ready surfaces (TiN, TiAlN, DLC for enhanced performance)
