摘要： An external component for timepieces or pieces of jewelry, made of a light precious alloy containing titanium and palladium, according to the atomic formula TiaPdbMcTd, where a, b, c, d are atomic fractions of the total, such that a+b+c+d=1. a is 0.44 to 0.55, b is 0.30 to 0.45, c is 0.04 to 0.24, and d is 0.001 to 0.03. The alloy includes at most two metals M, taken from among Nb, V, Fe, Co, Au, Pt. Each metal trace T has an atomic percentage of less than 3.00% of the total alloy, from among 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. The alloy contains at least 0.05% of boron, and contains at least 50% by mass of palladium.
