Tungsten Cemented Carbide Grade

How to choose the proper tungsten cemented carbide?
Selecting the proper tungsten carbide grade boils down to an educated compromise. The specifier, aware that no metal offers  the ultimate  in  everything  desired,  must determine  what  properties  are needed  most,  and  then  strike  the balance  that best meets his or her needs. How much toughness is needed? What about resistance to corrosion and shock? How important is wear and abrasion resistance? What design parameters must be considered?  What are the applied loads and stresses?  Is edge preparation a consideration?

Then add to this matrix considerations such as tungsten cemented carbide grain size, binder alloy percentage, and the addition of titanium, tantalum carbide, and other alloying elements. All of these variables have to be calculated to achieve the best compromise and result.

In general, many variables and conditions have to be considered in selecting the proper tungsten cemented carbide grade for tool, die and wear part applications. Every application should be evaluated carefully and individually to optimize the composition most likely to provide the right balance of hardness, wear, strength, toughness and corrosion resistance.
