These are probably the morphology and area roughness from the particles. Sn and Zn consist of spherical, smooth particles. The movement routine is for that reason absolutely free-flowing for these powders. The Mo, Mn and Bronze mentioned over consist of particles that has a rough surface, and irregular styles, which put their flowability in the area of quick-flowing. Unusually superior ffc values (Sn, Al powder) are probably final result from The reality that the set typical pressure is simply too small for these materials. It may therefore be attributed for the device options and it needs to be pointed out that in these scenarios the deformation from the particles can even have an influence.
