Diffusion bonded homogeneous powders are used to guarantee gigh mechanical characteristics.
Due to a processing called diffusion bonding, iron particles are connected with small particles of alloying elements i.e Ni, Cu, Mo. This bond is carefully controlled in order to guarantee that the powder maintains compressibility and flowability while increases homogeneity
