Description

Pt-10%Rh DPH is an oxide dispersion hardened grade of the traditional alloy Pt-10%Rh. The DPH alloy combines the advantages of excellent resistance to oxidation and corrosion with high strength at temperatures up to 1700°C. Despite the high strength, Pt-10%Rh DPH has excellent forming properties and a high degree of ductility under service conditions. In common with the other DPH materials from Heraeus, Pt-10%Rh DPH can be readily welded by all standard techniques, including tungsten inert gas (TIG), laser and electron beam welding. The strength of the alloy is largely maintained after welding.

Especially as a result of the high rhodium price in recent years, Pt-10%Rh DPH has replaced the non-dispersion hardened alloy Pt-20%Rh in many applications.

This material data has been provided by Heraeus.

"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.
