Description
 
May be used for 9 K & 14 K casting, which produces a Premium Pink finished color.
You should obtain excellent results by following a few simple instructions.

MELTING We do recommend pre-alloying all alloy and fine gold with aggressive stirring & fluxing to assure a uniform mixture.

Step : 1 Pre- Alloying (Fine gold + alloy) Temperature 1040° - 1050° C
1904° - 1922° F

Step : 2 Casting Temperature for 9 K – 14 K Alloyed Grain 990° - 1010° C
1814° - 1850° F

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

FLASK TEMPERATURE Normal recommended temperature in the range of 580° C to 700° C / 1076° F – 1292° F depending on size of flask, karat & type of jewelry.

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 For 9 K – 14 K quench 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. Use of aggressive acids causes stress corrosion and surface damage and is therefore not recommended.

REMELTING We recommend a 50% rejuvenation for re-melting.
