The Brief Introduction of Carbide Rod

February 01,2023

Cemented carbide is a composite material composed of a refractory metal compound (hard phase) and bonding metal (bonding phase) produced by powder metallurgy. Carbide rod is a new technology and new material. It is mainly used in the manufacture of metal cutting tools, the manufacture of wood, plastics required hardness and wear resistance corrosion resistance products, and other industries.




Process flow of carbide rod


Powder making→formulation according to the application requirements→wet grinding→mixing→crushing→drying→sieving→adding forming agent→re-drying→sieving to obtain a mixture→granulation→pressing→forming→low pressure sintering→forming→exterior Round grinding and fine grinding→size inspection→packing→warehousing.


Material performance characteristics of carbide rod


1. Use high-quality ultra-fine tungsten carbide and imported cobalt powder as raw materials.


2. Adopt the world's advanced low-pressure sintering preparation technology for standardized production.


3. High strength and hardness.


4. It has an excellent red hardness, good wear resistance, high elastic modulus, high bending strength, good chemical stability (acid resistance, alkali resistance, high-temperature oxidation), good impact resistance toughness, low expansion coefficient, thermal conductivity, electrical conductivity and Similar characteristics of iron and its alloys.


5. Unique new technology: Vacuum high temperature and high-pressure sintering. The product adopts pressure sintering in the final stage, which greatly reduces porosity, improves compactness, and greatly improves the mechanical properties of the product.
