Cemented Carbide Blade for Cutting Tools | Tungsten Carbide Industrial Blades Supplier
-
Cemented carbide blades are high-performance cutting tools made from tungsten carbide particles bonded with cobalt or nickel.
They offer extreme hardness, wear resistance, and thermal stability for industrial cutting applications.
They are widely used in metal cutting, woodworking, textile processing, and industrial machining.
Description
1. What is Cemented Carbide Blade
Cemented carbide, commonly known as tungsten carbide or carbide, is a composite material.
It consists of hard carbide particles (mainly tungsten carbide WC) bonded by a metallic binder such as cobalt (Co).
This structure makes the material extremely hard and suitable for high-speed cutting applications.
Cemented carbide blade is a high-performance cutting tool made from a metal matrix composite.
It is a pseudo-alloy produced through powder metallurgy.
Hard ceramic particles are cemented together by a metallic binder.
2. Key Properties of Cemented Carbide Blade
Extreme Hardness
It ranks just below diamond on the Mohs scale.
This allows the blade to maintain sharp cutting edges for a long time compared to HSS tools.
Thermal Stability
It can withstand high temperatures generated during cutting operations.
Prevents softening under high-speed machining conditions.
Wear Resistance
Ideal for abrasive materials such as fiberglass, MDF, and reinforced plastics.
Ensures long service life and stable performance.
3. Applications of Cemented Carbide Blade
| Type | Usage | Benefits |
| Circular Saw Blades | Cutting hardwoods, laminates, non-ferrous metals | Clean cuts, reduced sharpening frequency |
| Industrial Knives | Paper slitting, textile cutting, packaging | Reduced downtime and longer service life |
| Scraper Blades | Glue, paint, rust removal from surfaces | High durability and long edge retention |
| Milling Inserts | CNC machining and metal cutting | High-speed and high-efficiency material removal |
4. Key Performance Characteristics
Extreme Hardness
Ranks just below diamond on hardness scale.
Maintains cutting edge sharpness for extended periods.
Thermal Stability
Performs well under high cutting temperatures.
Resists deformation during high-speed machining.
Wear Resistance
Suitable for abrasive and reinforced materials.
Provides long service life in demanding applications.
5. Application Overview
