Process Of Cemented Carbide
How is cemented carbide made?
A powder metallurgic material
The manufacturing process begins with the composition of a specific cemented carbide powder mixture - tailored for the application.
The cemented carbide powder is compacted into a form. In a high-temperature sintering furnace, the tungsten carbide structure of the blank is shaped at precise temperatures for strictly defined periods. During this heat treatment, the tungsten carbide blank undergoes shrinkage of some 50% in volume.
The sintered Cemented Carbide component gains its final finish by additional grinding, lapping and/or polishing process.

Tungsten cemented carbide has very high strength for a material so hard and rigid. Its compressive strength is higher than virtually all melted and cast or forged metals and alloys.
Tungsten carbide is a class of materials widely used in drawing dies because of their superior strength, toughness and wear resistance.
When tungsten and carbon united they become one of the hardest of all carbides.
Flange generally refers to the four sides of a flat sheet of material are folded together into a box shape, but the four sides are folded up separately.
