Widia, also knows as cemented carbide or tungsten carbide, was registered by the company Krupp in 1926 and named as WIe DIAmant (as diamond). Cemented carbides are composed of a metal matrix composite used in the mechanical production where carbide particles act as the aggregate and a metallic binder (usually cobalt) serves as the matrix. The process of combining the carbide particles with the binder is referred to as sintering or Hot Isostatic Pressing (HIP).
The cemented carbide (HM) can be used for the realization of tungsten cutting tools for the industrial processes of turning, milling and drilling or in other applications where high hardness is required.
The carbide (HM) cutting tools are harder than the tools realized in steel or high speed steel (HSS) and able to endure higher cutting temperatures (1000° against 600°) and then permit higher speed cutting. A possible disadvantage could be the lower toughness compared to the HSS
The tungsten carbide manufactures produce carbide rods, carbide flat bars, inserts and carbide burrs then used for the realization of carbide cutting tools.
Sinter Sud is a carbide manufacturing company leader worldwide for the production of tungsten carbide products like rods, flat bars, inserts, tips, burrs for carbide cutting tools (drills, end mills, burrs, reamers) used for processes of drilling, milling and turning.
