There is a dissolving drawing for the binder--Cobalt(Co) when it is WEDM as given below.
 

Hardness It is the one of the important physical properties when it Comes to abrasive resistance.Higher Co content&finer Grain size the carbide is,harder it will be.

Density Density of pure tungsten is 15.6g/cm3,pureCo is 8.9g/cm3 More cobalt content the carbidehas,lower density it will be.

T.R.S T.R.S values increase with increasing ofbinder content,and decrease with decreasing of powdergrain size.

K1C K1c is a property can reflect the toughnessof carbide.The value increase with in creasing of Co&grain size.
