Product Introduction:
Hard alloy rod is hard alloy round rod, also called tungsten steel rod, simply tungsten steel round rod or hard alloy round rod. Hard alloy is a composite material which is produced by powder metallurgy and consists of refractory metal compounds (hard phase) and bonded metals (bonded phase).
Product Features:
1. The cemented carbide bar adopts the low-pressure sintering technology, and the quality is stable and reliable: the large sintering pressure can reach 100 kg force, and the internal pores of the alloy can be effectively eliminated, so as to obtain good densification of high hardness and high strength blank, and the temperature control system can effectively reduce the mass fluctuation.
2. Adopt automatic pressure relief and extrusion equipment, all kinds of bars can be produced.
3, fine grinding of the bar, can reach the mirror effect: the use of CNC grinding machine, can quickly remove the damage layer caused by polishing, improve the surface finish, can reach the mirror effect.
4, stable mechanical properties, easy to weld, high wear resistance and high impact resistance. These rods are used to manufacture cutting tools for metals, wood, plastics and other industries that require hardness and wear resistance.
Product application scope:
It is mainly used for manufacturing drill, integral end milling cutter, integral reamer, automobile special cutting tool, etc., but also can make carbide punch, mandrel and perforating tools, etc.
