Carbide Cutting Blade

FOTMA Industrial Cemented Carbide Blade: Custom Solutions for Extreme Applications

FOTMA tungsten carbide cutting blades are engineered for heavy-duty industrial environments like quarrying, logging, and paper mills. Built to withstand extreme wear, our custom-designed blades, circular saws, and cutters excel in crushing rocks, slicing wood, and processing fibrous materials. From massive ore fragmentation to high-speed pulp cutting, we deliver unmatched durability across industries.

Material Advantages of Tungsten Carbide Tipped Blade

1. High-Toughness Tungsten Carbide Matrix
   • Ultra-Coarse Grain WC: Particle size 3-8µm with 8%-15% cobalt/nickel binder, boosting impact resistance by 200% (impact value ≥40 J/cm²).
   • Cr3C2/VC Grain Inhibitors: Prevent WC grain growth under high temperatures, ensuring edge stability.
2. Corrosion-Resistant Coatings
3. Fatigue-Resistant Design

Density ≥14.5 g/cm³ (zero porosity), no micro-crack propagation under cyclic loads, lifespan 5-8x longer than standard blades.
