#PD3 Alloy
UNITED'S PD3 Palladium white alloy is a nickel free white master
alloy. PD3 is designed for 10K casting. The color produced will be a
moderate white, which should be Rhodium plated for optimum color.
PD3 alloy can be used in regular investment, but is somewhat better
using Phosphate bonded investment.
You should obtain excellent results by following a few simple
instructions.
MELTING
| Melt Temperature for 10K Alloyed Grain |
1000°- 1010°C |
1832°-1850°F |
| Melt Temperature for Alloying |
1050°- 1060°C |
1922°- 1940°F |
We do recommend pre-graining all alloy and fine gold before
casting to assure a uniform mixture.
FLASK TEMPERATURE
Normal recommended temperature for white gold.
FLUXING
Boric Acid is the recommended flux. Use as little flux as possible.
Do not use carbon fluxes or any fluxes designed for refining; i.e.
soda ash, saltpeter, etc. Avoid flux in bottom pour automatic
casting units.
QUENCH TIME
8 minutes
INVESTMENT REMOVAL
Most standard investment removers will successfully remove the
investment powder. UNITED'S Brite-Cast Investment Remover also works
very well.
REMELTING
We recommend 50% rejuvenation for remelting. Reuse will be limited
to a few melts.
NOTES
Melt temperature may vary with type of unit. This alloy is designed
for casting only.
