Preform and manufacturing process producing heterogeneous components with a first fraction (11) made from a first metallic material and having a cellular structure with stochastic or regular cells, and a second fraction (12) made from a second metallic material different from the first metallic material, in which the second fraction (12) at least partly infiltrates the cells of the first fraction (11). The second fraction is poured into the preform which also acts as a mould. The finished product after machining may have a unified surface of the second fraction or several zones exposing the second fraction, the first fraction, the cellular structure which is open or infiltrated with the second metallic fraction, or open zones, in a predetermined design.
Timepiece component comprising a skeleton foam made of rigid component parts of a first metallic material linked to one another to define an open cellular structure comprising outermost rigid component parts forming an outermost peripheral surface of the skeleton foam, the heterogeneous component further comprising a cast second metallic material filling the open cellular structure, wherein the cast second metallic material further forms a skin having a unified and homogeneous visible outer surface overlaying said outermost rigid component parts of the outermost peripheral surface of the skeleton foam of at least a portion of the open cellular structure.
Timepiece component obtained by a manufacturing process, comprising the steps of:
