The articlepresents data on thecomposition andselection of the optimaldevelopment of manufacturingsheet metalcomposite materialsfor the manufacture ofcutting discs.Proposeddiamondcompositionbased on a mixtureof powdersFe-Cu-Ni. Complexstudy included determination ofthe technological propertiesof powders,physical and mechanicalproperties of materialsby standard techniquesto study the structureof the samples.Structural studieswere carried outby methodsof metallography, X-ray, electron microscopy in transmissionand scanning electronmicroscopy.Optimization ofthe factorswas performed usinga mathematical model ofthe second order withthe use of symmetriccomposite designsBox-Benkin. The testsmadeinthe instrumentthroughthe abrasivecuttingsilicon wafers.
