Abstract (en)
[origin: WO2016107752A1] An external component (1) for a timepiece or jewellery item, made from lightweight precious alloy comprising titanium and palladium, in the atomic composition TiaPdbMcTd, in which a, b, c and d are atomic fractions of the total, such that a+b+c+d= 1, - a being between 0.44 and 0.55, - b being between 0.30 and 0.45, - c being between 0.04 and 0.24, - d being between 0.001 and 0.03, - in which said alloy comprises, at most, two metals M, chosen from Nb, V, Fe, Co, Au and Pt, - in which each trace of metal T has an atomic proportion of less than 3.0% of the total of said alloy, chosen from Nb, V, Mo, Ta, W, Fe, Co, Ni, Ru, Rh, Ir, Au, Pt, Cr, Mn, Cu, Zn, Ag, Al, B, Si, Ge, Sn, Sb and In, - said alloy comprising at least 0.05% boron, and comprising at least 50% by weight of palladium.
