Preparing high quality Pd950 alloy is a difficult task since
palladium (unlike platinum) is reactive with crucibles and
atmospheric gases. High quality melting equipment with precise
temperature, vacuum, and atmospheric control, as well as special
crucible materials are required.
Alloy suppliers like Legor have invested, researched and developed
these technologies to provide consistent quality alloys to their
Our metallurgists have not found iridium to be a viable replacement
for ruthenium in PD950. However, there are other alternatives to
ruthenium that have been developed that may be interesting to you
depending on your type of application.
