CASTING technical data [PDF]

FABRICATION technical data [PDF]

UNITED’S # HT 961 ALLOY is to be used for 18K casting, or hand-made (rolling), which produces a 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       1050° - 1060° C

1922° - 1940° F

Step : 2 Casting Temperature for 18 K Alloyed Grain 1010° C / 1850° F

UNITED’S # HT 961 ALLOY is a Pink master alloy designed for 18 K pink gold casting and rolling, which produces a pink finished color. Alloy # HT 961 is much easier to cast, fabricate and set stones compared to other colors.

KARATING The # HT 961 Pink Alloys and fine gold should be melted together in a clean crucible. Put the alloy in the bottom of the crucible and the fine gold on top. Initial melting temperature should be 1050º C – 1060ºC / 1922º F - 1940º F. Drop the temperature somewhat before pouring as listed below. Boric acid flux should be used to keep the metal clean during the melting process. The molten metal should be mixed well with a stirring rod before pouring to assure a good mix. A neutral or reducing cover gas is very helpful in melting pink gold alloys.

POURING TEMP 18 K - 1015ºC - 1030 ºC (Quench in water within 3 min for 18K)

FOR INGOTS 1860ºF – 1886 ºF
