#974 Alloy

Thank you for using UNITED'S alloys.

UNITED'S 974 ALLOY may be used for 10K & 14K white gold casting, which produces a white finished color. #974 is a high fluidity alloy that contains a silicon & boron as deoxidizers.

You should obtain excellent results by following a few simple instructions.

MELTING

We do recommend pre-graining all alloy and fine gold before casting to assure a uniform mixture.

FLASK TEMPERATURE
We suggest a slightly higher flask temperature for white gold.

FLUXING
Fluxing white gold is extremely important to pick-up oxides. Boric Acid is the recommended flux. 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
10 - 15 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 70% fresh - 30% scrap mix. White gold alloy has about 1/3 the reusability of yellow gold alloys.

NOTES
Melt temperature may vary with type of unit. This alloy is designed for casting only
