Crobalt® is a cast alloy that contains approximately 50% Cobalt. The remaining 50% consists of Tungsten, Chromium, their carbides and minor additives. Crobalt®offers substantial advantages over high-speed steels and cemented carbides in many applications. Crobalt®is formed by pouring molten metal into molds. The mold material (graphite, sand, shell investment) determines the cooling rate. The cooling rate controls the microstructure and physical properties. Crobalt® does not require any heat treatment since its properties are established by its composition and casting technique.
Crobalt® is a Cast Cobalt-Base Alloy. High-Speed Steels are Iron-Base Alloys. Cemented Carbides are pressed and sintered carbides of Tungsten, Tantalum and Niobium in a Cobalt matrix. Crobalt® is not a High-Speed Steel, nor is it a cemented Carbide. Crobalt’s® place in the cutting tool spectrum is between the high-speed steels at the low
speed ranges and cemented carbides at the higher speed ranges.
