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.
