Product Description
Tungsten Carbide Rod with R2 Arc Profile
Product Overview
The Tungsten Carbide Rod with R2 Arc Profile is a high-performance hard alloy rod precision-machined from ultra-fine grain tungsten carbide material. Featuring a precisely designed R2 arc contour at the front end, this product combines exceptional wear resistance, high rigidity, and excellent impact toughness. Specifically developed for demanding wear environments and high-precision machining applications, it is widely used in mechanical processing, mold manufacturing, precision guiding, and wear-resistant components, making it an ideal choice for enhancing equipment performance and service life.
Key Features and Advantages
- Exceptional Wear Resistance & Long Service Life: Manufactured from high-purity tungsten carbide with hardness exceeding HRA 90, offering wear resistance that far surpasses high-speed steel and other alloy steels, significantly extending replacement cycles and reducing operational costs.
- High Rigidity and Stability: Features extremely high modulus of elasticity and compressive strength, effectively resisting bending deformation under high-speed or heavy-load conditions to ensure precision and stability in machining operations.
- Excellent Impact Resistance: Optimized cobalt binder formulation and sintering process enhance material toughness while maintaining high hardness, allowing it to withstand intermittent impact loads.
- Precise R2 Arc Design: Precision-ground R2 arc contour with accurate dimensions and smooth transitions facilitates stress distribution, reduces stress concentration, and is ideal for machining, guiding, or forming specific profiles.
- Superior Surface Quality: Precision grinding or polishing results in high surface finish and low coefficient of friction, further enhancing wear and galling resistance.
Typical Application Areas
- Mechanical Machining: Wear-resistant tool setting rods, profile rods, or shanks for special cutting tools in lathes and milling machines
- Mold Industry: Wear-resistant inserts, guide rods, or ejector pins in molds, particularly suitable for mold cavities requiring arc transitions
- Automation Equipment: High-precision guide shafts, wear-resistant rails, and inspection probe rods
- Wear-Resistant Components: Replacement parts for heavily worn areas in textile, packaging, metallurgy, and other industrial equipment, including bearings, bushings, and roller shafts

Usage and Selection Guidance
- Selection Guide: Choose appropriate rod diameter and length based on actual application load, impact conditions, wear requirements, and installation space. For applications with significant lateral forces, larger diameter products are recommended.
- Installation and Fit: Use with high-hardness, wear-resistant bushings (e.g., tungsten carbide bushings). Ensure proper fit tolerance (typically slight clearance or light press fit) and maintain adequate lubrication.
- Precautions: Avoid prolonged use in extreme high-temperature oxidizing environments. Prevent severe direct impact or overload shock. During installation, ensure the arc end orientation aligns with design requirements.
