United
Precious Metal Refining, Inc.
Ultraloy™ #UA1, UA2, UA3, UA5
Thank you for using UNITED'S alloys.
UNITED'S ULTRALOYTM series is a specialized group of silicon
deoxidized yellow gold casting alloys, designed for 10K & 14K.
You should obtain excellent results by following a few simple
instructions.
MELTING
| Melt Temperature for 14K Alloyed Grain |
940° - 970° C |
1724° - 1778° F |
| Melt Temperature for 10K Alloyed Grain |
960° - 990° C |
1760° - 1814° F |
| Melt Temperature for Alloying |
1040° - 1050° C |
1904° - 1922° F |
We do recommend pre-graining all alloy and fine gold before
casting to assure a uniform mixture.
FLASK TEMPERATURE
Normal recommended temperature.
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
15 - 20 minutes
INVESTMENT REMOVAL
Most standard investment removers will
successfully remove the investment powder. Fluoric-based investment
removers are the best for removing the silicon oxide invisible
coating. UNITED'S Brite-Cast Investment Remover also works very
well.
REMELTING
We recommend a 50% rejuvenation for remelting, unless
our #99 Alloy Replenisher is used.
NOTES Melt temperature may vary with type of unit. This alloy is
designed for casting only.
