#544
Alloy
Thank you for using UNITED'S alloys.
UNITED'S 544 ALLOY may be used for 10K, 14K & 18K casting, which
produces a pink / red finished color.
You should obtain excellent results by following a few simple
instructions.
MELTING
| Melt Temperature for 10, 14 & 18K Alloyed Grain |
990° -
1020° C |
1814° - 1868° 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
We recommended a slightly higher 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 minutes for 10K & 14K
3 - 5 minutes for 18K
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.
NOTES
Melt temperature may vary with type of unit. This alloy is
designed for casting only.
