Period 5 element electrical contacts and the production of thick-film resistors. A minor application of ruthenium is its use in some platinum alloys. Rhodium is a chemical element that is a rare, silvery-white, hard, and chemically inert transition metal and a member of the platinum group. It has the chemical symbol Rh and atomic number 45. It is composed of only one isotope,Rh. Naturally occurring rhodium is found as the free metal, alloyed with similar metals, and never as a chemical compound. It is one of the rarest precious metals and one of the most costly (gold has since taken over the top
Institute of Cast Metals Engineers Institute of Cast Metals Engineers The Institute of Cast Metals Engineers (ICME), originally the British Foundrymen's Association is a British professional engineering institution founded in 1904. It publishes the Foundry Trade Journal, which was established in 1902. It was founded as the British Foundrymen's Association in 1904. It was given a Royal Charter on 25 November 1921. On 11 October 2000, it changed its name to the Institute of Cast Metals Engineers. It is licensed by the Engineering Council to assess candidates for inclusion on its Register of professional Engineers and Technicians. The Institute's address is ICME Metalforming Centre, 47
