LUX105
Master alloy suitable for the production of 585‰ and 750‰ white gold alloys (Ni20Zn18). The resulting alloy is for the production of investment cast items without stones in place. Rhodium plating is suggested only for the 750‰ gold alloy, while it is not strictly required for the 585‰ gold alloy, thanks to the good intensity of white; however, final decision is left to the producer. Only the 750‰ gold alloy lends itself for hardening. 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 standard.
