strong hardness tungsten carbide bar for end mill

Tungsten carbide bar is a sintered metallurgical product of powder form. It is manufactured in vacuum or Hydrogen reduction furnace with refractory tungsten material (WC) micron powder as the main ingredient and Cobalt (Co), Nickel (Ni) or Molybdenum (Mo) as the binder. It has many excellent characteristics such as high hardness and strength, good wear and corrosion resistance and salient stability under high temperature (even at 500 ºC it is essentially unchanged and at 1000 ºC it is still of high hardness).
