Characteristics and applications of cemented carbide round bars
Carbide round bars have high hardness, excellent wear resistance and good thermal stability, and is widely used in cutting tools, molds, wear-resistant parts and other fields.
- Basic characteristics of cemented carbide round bar materials:
Carbide round bar materials occupy an important position in industrial production due to their excellent physical properties. This material is mainly made of refractory metal carbides (such as tungsten carbide, titanium carbide) and metal binders (such as cobalt, nickel) pressed and sintered by powder metallurgy methods. Its notable features include high hardness, excellent wear resistance and good thermal stability. These properties make cemented carbide round bar materials ideal for manufacturing high-performance cutting tools, molds and wear-resistant parts.

- Application fields of cemented carbide round bars:
- Tool manufacturing: The high hardness and wear resistance of cemented carbide make it an ideal material for manufacturing cutting tools. Whether for turning tools, milling cutters or drills, carbide round bars offer excellent cutting performance and a long service life. If you plan to make milling cutters for stainless steel, I would highly recommend grade BT25UF. This one is a high-end grade.
- Mold industry: In mold manufacturing, cemented carbide round rods are favored for their high strength and wear resistance. It can be used to make stamping molds, die-casting molds, etc. to ensure that the mold maintains high precision and stability during long-term use.
- Wear-resistant parts: Carbide round rods are also widely used in the manufacture of various wear-resistant parts, such as shafts, pins, gears, etc. These parts can still maintain good performance in harsh working environments, effectively extending the service life of the equipment.
- Future development of cemented carbide round bars:
With the continuous advancement of science and technology and the growing industrial demand, carbide round bar materials will continue to play a key role. In the future, with the continuous development of new material technology, the performance of cemented carbide is expected to be further improved, bringing more possibilities to the industrial field. In short, cemented carbide round bar materials occupy a pivotal position in modern industry with their unique physical properties and wide range of applications. Whether it is tool manufacturing, mold industry or the production of wear-resistant parts, carbide round bars have shown their indispensable value.
