A multi-coating step immersion coating process for producing a coating of a noble metal on a non-noble metal substrate, wherein the noble metal is of a predetermined amount expressed as a percent of the total weight of coated product, and wherein the non-noble metal substrate is in the form of fine particles or a powder is disclosed. The process also utilizes inter-plating step and post-plating step rinsing step sequences which together with the use of the plurality of coating steps consistently results in high quality product having a uniform coating, excellent corrosion resistance and excellent electrical conductivity. Use of the coated products produced according to the process in a variety of electrically conductive compositions, including plastics, adhesives and inks, and in plastic and resin based electromagnetic shielding materials is also disclosed.
