Message:: [QUOTE="John Burgess, post: 8239413, member: 105098"]Palladium Plus  is used as a dental alloy. It's mainly cobalt 66%, plus chromium 27% and molybdenum 5% So that only leaves 2% for the palladium. that's not the same as what's used for class rings though I see it can be up to 20% when they have been assayed. and that's the thing, all of these ring alloys are trademarked names and proprietary information on what the exactl composition of the alloy is, without assay of the alloy there's really no way to tell how much precious metal is in them. I'd check around locally for an alloy assayer and see what they charge to test, then you'd know for sure what is the precious metal content. if it's 20% certainly you wouldn't want the confusion of the dental alloy with a refiner and them giving you the 2% price for it, then taking it for assay later on to find they made some money off you.[/QUOTE]
