FAQ

Q:What is cemented carbide ?

A: Cemented carbide is a hard material used in machining tough materials such as carbon steel or stainless. Carbide tools can also withstand higher temperatures .

 

Q: Which grades are useful in metal forming applications?

A:  Grades employed for metal forming applications are typically based on coarse grain sizes (3 to 8 mm) and high binder contents (15 to 30 wt. %).

 

Q: Which grades are useful in earth drilling or boring applications?

A: The best compromise is usually arrived at by using grades that are based on coarse grain sizes (3 to 8 mm) 

and relatively low Co levels (6 to 16 wt. %).
