Characteristics of carbide

Carbide are widely used as wear-resistant parts, powder metallurgy molds, hardware stamping dies, wire drawing dies, etc. They are a class of materials made by sintering hard metal compounds (WC, TiC, TaC, NbC) as the hard phase and metallic cobalt as the binder phase through powder metallurgy.

Carbide have the following characteristics:

1. They have high hardness (hardness can reach 86-93 HRA at room temperature), high hot hardness (up to 900-1000°C), and excellent wear resistance. Cutting tools made of carbide have cutting speeds 4-7 times higher than high-speed steel tools and tool life 5-8 times higher. They can cut hard materials with a hardness of about 50 HRC.
   
2. They have high compressive strength (up to 6000 MPa), but relatively low bending strength.
3. They have good corrosion resistance (resistant to atmospheric, acid, alkali corrosion, etc.) and oxidation resistance.
4. They have a low coefficient of linear expansion.

Due to the high hardness of carbide, they cannot be processed using conventional cutting methods. Special grinding wheels, electrical discharge machining (EDM), wire cutting, CNC, etc., are commonly used. Carbide parts are usually used as separate mechanical components or mold parts and are assembled using brazing, mechanical clamping, or hydraulic embedding.
