- ULTRAPACAdmixing alloying elements in powder form is a technique known and practiced for years. Depending on particle size distribution and particle shape of the plain iron powder, there is the risk of segregation, and the optimum effect of alloying elements (Cu, Ni, Mo) is not always achieved. I.P.M.C has developed diffusion bonded alloyed steel powders employing iron powder containing Ni and Mo as base material. Copper is added to the base powder, and after mixing, Powder receives reduction treatment. Formation of diffusion bonds between copper and Iron base powder prevents segregation. We produce two types of ULTRAPAC powder under commercial names of ULTRAPAC-LA and ULTRAPAC-LE with the following properties: ULTRAPAC-LA CHEMICAL ANALYSIS (%Wt.)(Max)
