Introduction
Cast tungsten carbide (CTC) welding rods are engineered to provide exceptional abrasion resistance in extreme wear environments. Unlike conventional welded coatings, CTC rods deposit a dense layer of coarse tungsten carbide granules onto substrate surfaces through oxygen-acetylene or arc welding processes. These rods are widely used in mining, oil drilling, agriculture, and construction to extend the service life of critical components.
| Type | Range of Particle Size (mesh) | Pipe o.D. (mm) | Pipe Length (mm) | Powder (%) | Steel Pipe (%) |
| YZ2 | -20~+30 | 7~7.15 | 390/600 | 60~70 | 40~30 |
| YZ3 | -30~+40 | 6~6.15 | 390/600 | 60~70 | 40~30 |
| YZ4 | -40~+60 | 5~5.15 | 390/600 | 60~70 | 40~30 |
| YZ5 | -60~+80 | 4~4.15 | 390/600 | 60~70 | 40~30 |

CTC rods consist of macroscopic tungsten carbide particles (typically 0.5-3 mm) embedded in a ductile matrix (usually nickel or cobalt-based). This unique structure offers:
- Extreme Hardness: Carbide granules reach 2,500-3,000 HV, providing superior resistance to abrasion, erosion, and impact.
- High Deposit Density: The coarse carbide distribution minimizes binder exposure, reducing material loss in abrasive slurries.
- Thermal Stability: Retains hardness up to 600°C, making it suitable for high-temperature applications.
- Longer Service Life: Outlasts welded steel surfaces by 5-8 times in abrasive environments
1. Mining and Mineral Processing:
- Screens, crusher liners, and conveyor screws are subjected to heavy abrasion.
2. Oil and Gas Drilling:
- Drill pipe hardfacing, stabilizer blades, and tool joints to combat formation wear.
3. Agriculture:
- Plowshares, tiller blades, and harvester components exposed to soil abrasion.
4. Construction:
- Concrete mixer blades, bulldozer teeth, and excavator bucket liners.
Cast tungsten carbide welding rods remain the gold standard for abrasion protection in industrial applications. By selecting the right rod composition and adhering to proper welding techniques, operators can significantly enhance the durability and performance of wear-prone components.

Why Choose Our CTC Rods?
Zhuzhou Better’s cast tungsten carbide welding rods are manufactured using vacuum refining and granular sintering technologies to guarantee:
- Optimal carbide morphology (blocky, non-angular granules).
- Low oxygen content (<100 ppm) for improved weldability.
- Customizable granule sizes (e.g., 0.5-1.0 mm for fine surfaces, 1.5-3.0 mm for severe abrasion).
