Abstract
The invention relates to a timepiece component (1) comprising at least one portion (3) machined by chip removal. Said portion (3) is made of a non-magnetic copper alloy in order to limit its sensitivity to magnetic fields, said copper alloy containing between 10 wt % and 20 wt % of Ni, between 6 wt % and 12 wt % of Sn, X wt % of additional elements, wherein X is comprised between 0 and 5, and the remainder is Cu. The invention concerns the field of timepiece movements.
