FAQ
What are the effects of corrosion?
We checked a cemented carbide made 20 years ago, and verified 20 microns worth of corrosion.
Only the surface was corroded, so we were able to remove it by reprocessing it.
However, there are cases where some corrosion cannot be removed due to working environments, so we recommend regrinding if the corrosion is 0.1mm or greater. If storing after regrinding, ensure that all processing liquids have been removed and dried. Apply the carbide with rust preventive oil or paper, or cover in alumina powder.

Why does the amount of Co and WC particle size affect the thickness of the heat affected layer?
It is thought that when Co is in large quantities the fusing point is lowered, which increases the amount that melts and thickening the damaged layer.
It is also thought that when WC particle size is small, the material becomes easier to melt due to the volume effect, which thickens the damaged layer. -
What are the advantages of using cemented carbide tools?
As cemented carbide is characterized by its resistance to loss of hardness at high temperatures, its performance is not easily deteriorated even when used for machining at high speed that cause tools to have high temperatures.

What is the difference between cemented carbide and ceramics?
The hardness of ceramics approaches that of diamond, the hardest mineral on earth. If the hardness of diamond is 10, ceramics exhibit a hardness of 9 or higher, which is harder than tungsten and other hard metals. The difference in composition also results in a heavier weight in the case of cemented carbides. However, cemented carbides can be made with various characteristics depending on tungsten carbide (WC) particle size, the amount of bonding material, and additives, so it is possible to select the most suitable grade for the application from a wide range of available grades.
