WA12B5 is a Proderma nickel-free, palladium-free master alloy for 375‰ (9 Kt) white gold jewelry, designed for lost-wax casting in closed and open systems.
WA12B5 is particularly suitable for stone-in-place casting.
The color of 375‰ gold made using WA12B5 shows a premium white color grade (Yellow index: 17.6). In 375‰ title it is not necessary to proceed with rhodium plating deposition on surface in order to ensure maximum whiteness on the final jewel.
The alloy is not suitable for age-hardening.
WA12B5 has a medium level of deoxidizers, this makes it suitable for casting in closed and open systems.
