Carbide round bar, also known as carbide rod, is a kind of carbide (WC) as the main raw material, coupled with other precious metals and paste phase by powder metallurgy method of sintering made of high hardness, high Strength of the alloy material, widely used in the field of national production and processing, such as tungsten steel drill.
Carbide round bar is a non-ferrous metal carbide (tungsten carbide, titanium carbide, etc.) as the matrix, iron group metal as a binder, powder metallurgy method of production of a multi-phase composite material, Carbide Round Bar which is characterized by high hardness, Good wear resistance, high mechanical strength; corrosion resistance and oxidation resistance, acid and alkali; expansion coefficient is small, point thermal conductivity and thermal conductivity and iron and ferroalloy similar.
Carbide classification according to its composition and performance is divided into tungsten cobalt, Carbide Round Bar tungsten cobalt and titanium, general category, titanium carbide, steel.
Carbide round bar material is generally tungsten cobalt alloy, tungsten cobalt alloy has good toughness and the appropriate wear resistance, so the carbide rod is mainly used for wire, bar processing with the drawing die. But also for cast iron, non-ferrous metals and their alloys and non-metallic materials are not flat surface and intermittent cutting rough car, fine fine grinding, the general hole and deep hole drilling, reaming and production of woodworking tools and so on because the carbide Rods with good toughness and wear resistance, carbide rods for wire and tube drawing die parts stamping die, motor stator and rotor, EI steel, LED frame stamping and other processing materials. Carbide round bar is a kind of carbide material, generally need to carry out in-depth processing to produce the required high-precision products, Carbide Round Bar such as carbide inlaid, it is by the carbide rod through the fine grinding process Thus becoming a high-precision mold parts, so further carbide ball is a carbide material.
Carbide round bar with the following characteristics
1, processed into a longer die life (high fatigue strength, not prone to stress concentration)
2, good life stability (crack occurrence and expansion time delay)
3, adhesion, bite burning significantly reduced (lubricant generated by the corrosion is extremely slight)
4, wire cutting EDM process greatly improved corrosion resistance (anti-electric processing corrosion ability)
5, raw material purity of 99.95% or more, Carbide Round Bar very little impurity content, Carbide Round Bar round rod physical properties more stable.
