Powder Metallurgy Engineering Properties

Most properties of a powder metallurgy (PM) part are closely related to its final density. This density is the mass per unit volume of the part expressed in grams per cubic centimeter (g/cm). Normally, the density of structural parts is reported on a dry, un-impregnated basis, while the density of bearings is reported on a fully oil-impregnated basis.Get price

Abrasive

An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing[1] which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In Get price
