Carbide round bar manufacturer

Carbide round rods are used as the base material to produce a wide range of products, such as carbide punches, needles, needles, milling cutters, etc.

Cemented carbide round bar is a kind of alloy material with high hardness and high strength, which is made of cemented carbide (WC) as the main raw material, plus other precious metals and pasting phases, which are pressed and sintered by powder metallurgy. The field of national production and processing.

Tungsten carbide round rod, its main components are tungsten carbide powder, cobalt powder and binder mixed with other very small amount of precious metals and then sintered at 1300 degrees by powder metallurgy method, with high hardness, high strength, durability High temperature, high wear resistance and good impact toughness, tungsten carbide round rod is mainly used to make high-quality tungsten steel drill bits and tungsten steel milling cutters, gong cutters, drill bits and industrial machinery and equipment for processing ferrous metals. Wear parts.

1. The purity of the raw material is over 99.95%, the impurity content is very small, and the physical properties of the board are more stable.

2. The density of the round bar is uniform: it is pressed by a 300Mpa isostatic press, which effectively prevents the occurrence of pressing defects, and the density of the round bar blank is more uniform.

3. Using spray drying technology, the material is protected by high-purity nitrogen under fully sealed conditions, which effectively reduces the possibility of oxygenation during the preparation of the mixture, with better purity and less dirt.

4. Using cryogenic treatment technology, the internal metallographic structure of the plate is improved, and the internal stress can be greatly eliminated to avoid cracks during the cutting and forming process of the plate.

5. The compactness of the round bar is excellent, and the strength and hardness indicators are excellent: the ship low-pressure sintering technology is adopted to effectively eliminate the pores inside the plate, and the quality is more stable.

Cemented carbide rods have a series of excellent properties such as high hardness, high wear resistance, high strength, bending resistance, and long tool life. Cemented carbide rods are the blanks for making drill bits and cutting tools, and currently the powder extrusion molding process is mainly used. Nowadays, it is widely used in the production of drill bits, automotive tools, printed circuit board tools, engine tools, integral end mills, integral reamers, engraving knives, etc., and can also be used to make punches, mandrels, tips and perforation tools.

With the sharp increase in market demand, ultra-fine-grained cemented carbide rods have been more and more widely used. In the field of high-speed cutting, due to the high standard requirements for tool safety, reliability and durability, the internal and surface quality requirements of solid carbide tools are also more stringent. With the continuous improvement of the intrinsic quality of cemented carbide rods, especially ultra-fine cemented carbide materials, the quality of the overall cemented carbide tool surface has received more and more attention.
