I'm looking for recommendations for semi-precious metal for crown n bridge. I've been using Euro from Argen forever. But am now looking for something less expensive for a new client .

I liked Superior by Jensen. If they have a gold fetish there is also Superior Plus with 1% gold.

Superior is 50%palladium, 25%silver. And was about $800/oz when I last used it in 2015.

It depends on how much silver your porc can handle without greening, also as you know, the cte range of your porc.

I'm using Jensen Stability which is expensive due to the high Pd and 2% Au. It, the market, is @ about 1400. and 1475. per ounce.
I'll probably try Superior which is cheaper due to the higher silver, lower Pd and no Au content until the market calms down. Maybe I'll even stick with it?

I am sure this alloy is out of reach, today, with the palladium quoting higher than Gold on the markets... Some high gold alloys are cheaper than alloys with palladium mixed in! I use Evolution lite, which pretty much doubled in cost over the last three years... But since I charge per .dwt, with a mark up, I dont really care...

My Argen rep mentioned an alloy they invented to counter the high gold price. Don't remember the name, though. (Alloy, not the rep's name... :cool:)

As 'Car' says, depending on your porcelain you have different options. in other words, make sure the CTE's match up. High silver alloys are usually a bit mote problematic (discoloration). As are high palladium ones, due to the intense oxide layer (but due to high cost of palladium that weeded itself out pretty much). So, that actually narrows down your options. Either you go NP or stick to a 'low cost' high noble, like Evo lite.

PS, I never thought I would say that: Thankfully we have Zirconium today...

Had not kept track of the metal prices. Thanks. Guess it's time to turn in the scrap I have from floor sweeping before I started my own.


Just gotta get all the pine needles and such out of it.

Boss was real nice about that. If it went in the floor and got swept up, it was mine.

We use Argen also and have switched to their new Platinum Plus. Nice alloy and great pricing. Pay attention to the firing programs to get good results. 20% Platinum, 5.7% Ruthenium, 43.5% Cobalt, 29.3% Chromium.

You need to set a new programs for degassing and opaquing. When we got the alloy we had no tech sheet with it and ran our normal programs. This alloy runs at a slightly higher temp to get a good oxide layer. If run to low it has a very dark oxide.

Any discoloration or margin creep ?

I am trying the Argen Platinum Plus. 4th attempt was a charm.. What I learned along the way.
pre heat crucible
1/4 to 1/2 inch inner torch cones
keep flame 1 1/2 inch away
use an 8g sprue
try not to remove flame from metal while melting.
ingots will not flow into one ball, more like casting Rex 3.. cast after it slumps like a jelly bean ,,If the metal rolls in the crucible its to hot.

I use Argen and use their SLM platinum + alloy. I've grown very fond of not investing and casting.

In the last year I've used these alloys from Argen due to the rising price of palladium.
Argelite 75+6
Argelite 61+3
Argelite 60+
Argedent Bio 720pf (72 Au, 13.9 Pt, 10.5 Ag)

I'm curious if Argen or its competitors will now be producing more platinum based pfm alloys?
