If you ask the question so non-specific, then they get a lot of answers that you use most often only conditionally.
Correct you can only answer the question, if they make it clear what objective they are pursuing - higher productivity, improved surface finish or greater machining accuracy. You can go to the cause, of course, so that they want to use and find out boron carbide, the benefits it brings. Note, however always that the use of powder requires additional costs in plant engineering and the wear of many components is increased.
aluminium powder (PGM WHIT 3) can be applied due to addition of aluminium powder in the dielectric enhances machining efficiency by making discharge breakdown easier and enlarges discharge gap.
