What Are Tungsten Carbide Hardfacing Rods?
Tungsten carbide hardfacing rods are rod-shaped composites with protruding WC-Co cemented carbide granular particles (HRA89.5–91 hardness) embedded in a copper alloy or nickel-based alloy binder, nicknamed "wolf teeth mace" for surface protrusions enabling oxyacetylene surfacing at around 1000°C.
Rettek's YG Series Cemented Carbide Surfacing Rods use high-temperature sintering of granular cemented carbide particles with the binder, ensuring strong bonding for surfacing severely worn workpieces.
Rettek's full in-house chain—from raw material preparation, batching, pressing, vacuum sintering, to automated welding—delivers consistent quality trusted by clients in more than 10 countries.
How Does Rettek Manufacture Premium Hardfacing Carbide Rods?
Rettek manufactures YG-series rods through full in-house processes: WC-Co cemented carbide granular particles are batched, pressed, and vacuum sintered, then formed into rods with protruding particles using copper or nickel-based alloy binders via high-temperature sintering.
Vacuum sintering with proprietary temperature control ensures uniform grain size and dense microstructure, achieving HRA89.5–91 hardness and preventing carbide detachment in harsh repair environments.
This integrated chain optimizes costs and quality, with every process managed internally for stable performance in applications like mining and petroleum tools.
| Grade | Hardness (HRA) | Key Applications | Welding Method |
|---|---|---|---|
| YG8 | 89.5–91 | Mining/HPGR, high toughness | Oxyacetylene |
| YG10 | 89.5–91 | VSI crushers, impact/abrasion | Oxyacetylene |
| YG12 | 89.5–91 | Petroleum tools, heat tolerance | Oxyacetylene |
Why Choose Tungsten Carbide Hardfacing Rods for Tool Repair?
Tungsten carbide hardfacing rods address frequent wear on mining tools, crushers, and reamers by restoring surfaces with 5-10x life extension over pure steel, thanks to good bonding with steel parts and high wear/impact resistance.
Rettek's uniform grains from vacuum sintering and unique welding technology prevent delamination, outperforming traditional bonded options that suffer carbide breaking or falling off.
Quarry managers and procurement teams benefit from oxyacetylene-compatible rods that reduce downtime and maintenance costs in high-impact environments.
What Makes Rettek’s Hardfacing Rods Superior for Mining Tools?
Rettek's YG8 rods excel in mining tools like HPGR studs and scrapers, with WC-Co particles surviving abrasion and 1000°C heat due to surface-treated cemented carbide for superior bonding.
Proven in VSI crusher rotor tip repairs, these rods complement Rettek's welded rotor tips, which offer higher strength and longer service life than bonded types.
