Embodiment Construction
[0015] Unless otherwise stated, the compositions in this specification are compositions in mass percent.
[0016] The invention relates to a timepiece component 1 , in particular a wheel set, comprising an axle-like portion 2 comprising at least one pivot 3 around a pivot axis D.
[0017] As for the material of the shaft portion, it is preferable that its Vickers hardness is between that of copper / beryllium alloy (380HV+ / −20) and that of 20AP steel or the like (740HV+ / −30).
[0018] According to the invention, at least the material forming the shaft-shaped portion 2 is a non-magnetic alloy containing at least silver and palladium and having a Vickers hardness greater than 450 HV.
[0019] In a particular embodiment, part 1 is completely non-magnetic.
[0020] In a particular embodiment, the shaft-like portion 2 runs through the entire length of the part 1 in the direction of the pivot axis D. As shown in FIG.
[0021] More specifically, the shaft-like portion 2 carries at le...
