LUX135
Master alloy suitable for the production of 750‰ white gold alloys (Ni30Zn14). The resulting alloy is for the production of investment cast items without precious stones. Rhodium plating is not necessary, thanks to the excellent intensity of white; however, final decision is left to the producer. All the most common investment casting techniques can be used. Progold does not guarantee product compliance with REACH regulation, Addendum XVII, n.27, when using test method provided for by EN 1811:2011+A1:2015 standard.
