OR129W is an Ultracast master alloy for 375-585-750‰ (9-14-18 Kt) red gold jewelry, as an all-purpose formulation.

OR129W is suitable for lost-wax casting in closed systems. It is suitable for continuous casting and for ingot casting of semi-finished items such as sheet, wire, tube. The main processes of 375-585-750‰ gold made using OR129W are massive chain, hollow chain, stamping, blanking, TIG tube, cladding, CNC and lathe production.

The color of 750‰ gold made using OR129W shows a pink hue. The color of 585‰ gold made using OR129W shows a hue, typically known as “Russian red” color. Also, in title 375‰ the alloy has a pink hue.

OR129W offers a very high level of grain refinement, useful to avoid brittleness problems, which are common in traditional 750‰ red gold alloys.

The hardness of 750‰ gold alloyed with OR129W can be greatly increased by means of a heat treatment. The alloy is not suitable for age-hardening in lower titles.

OR129W has extremely high shininess and lustrous color after finishing.
