Abstract (en)

[origin: WO2018001564A1] A white gold alloy of the composition (Au1-a-bAga(Pd1-cPtc)b)100-x-y(Cu1-d- eLdMe)x(Si1-fGef)y has been produced in which L represents In, Ga or Sn or Ld represents L1 d1L2 d2 or L1 d1L2 d2L3 d3, wherein L1, L2 and L3 are selected from the elements In, Ga, or Sn; M represents one or more elements of the elements Ni, Co, and Fe; x and y are at%, wherein x = 10 - 30 at% and y = 10 - 16.3 at%; (100-x-y), x, and y can contain unavoidable trace impurities; a, b, c, d, e, and f are a fraction of 1; a = 0.02 - 0.20, b = 0 - 0.1, c = 0 - 1, d = 0.02 -0.40, d1 = 0 to 0.4; d2 = 0 to 0.4; and d3 = 0 to 0.4, where d1 + d2 + d3 = d, e = 0 - 0.12 (total fraction of the elements Ni, Co, and Fe) and f = 0 - 0.40. The white gold alloy is suitable for a broad range of solid glass forming processes and for jewelry applications.
