FAQ
What is the difference between cemented carbide and HSS?
Cemented carbide is an alloy with high hardness, heat resistance and strength. HSS, on the other hand, generally has relatively lower strength and heat resistance, but has higher impact resistance.
As their raw materials and manufacturing methods differ, there is a significant difference in costs between the two materials.
Selecting the suitable material is recommended though considering the application and the timing of replacement after installation.

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.
-
How do you store cemented carbide products?
For cemented carbide materials:
Storing at room temperature is fine. (Less than 300 in Celsius, as cobalt oxidizes at that temperature)
Humidity will leads to rusting, so we recommend storing the materials in an area with low humidity.
For complete metal molds:
Cemented Carbide corrosion can occur from grinding fluid, lubricating liquid, or other liquids.
If the grinding or lapping surface is not stored properly, corrosion may occur.
Store using a rust preventive oil or paper. -
What is the main component of cemented carbide?
The main component is tungsten carbide (WC), which becomes cemented carbide after bonding with metallic binders such as cobalt and nickel.
Additives such as chromium (Cr) are added to these alloys to create cemented carbides with various characteristics.
