PtRh20 soft annealed (+A)

The material PtRh20 (in the literature also Pt20Rh, Pt80Rh20 or PtRh80/20) is used for highly stressed laboratory equipment, catalysts, electrodes, glass fiber nozzles and lining materials, for crucibles, casings and stirrers in viscometry as well as for glass melting tanks. The mechanical, thermal and corrosive resistance increases with increasing rhodium content. An advantage of the platinum-rhodium alloy is that even in an oxidizing atmosphere only a minimum of weight loss occurs. The material is ductile, corrosion-resistant, oxidation-resistant and high temperature resistant. It is machinable, roll-cladable and conditionally deductible from the gas phase.
