Description

The material PtRh30 (in the literature also Pt30Rh, Pt70Rh30 or PtRh70/30) is ductile, corrosion-resistant, oxidation-resistant up to approx. 1000°C, abrasion-resistant, hardenable and resistant to high temperatures. It is used for highly stressed laboratory equipment, electrodes, for thermocouples (pairing PtRh30 / PtRh6 up to 1750°C), glass fiber nozzles and lining materials, for crucibles, casings and stirrers in viscometry and 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.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
