STAINLESS BRONZE ALLOY AND ITS USE IN GALVANIZED PRODUCTS

The present invention describes a copper/Tin-based alloy containing Pt and optionally Zn and/or Pd having colorimetric coordinates that can be modulated from white to yellow to pink and exhibiting striking hardness and thus wear resistance characteristics. The invention also relates to a particular...

Beschreibung
Zusammenfassung:	The present invention describes a copper/Tin-based alloy containing Pt and optionally Zn and/or Pd having colorimetric coordinates that can be modulated from white to yellow to pink and exhibiting striking hardness and thus wear resistance characteristics. The invention also relates to a particular sequence of galvanic deposits, wherein a first coating consisting of a Nickel-Cobalt-Phosphorus based alloy is underlying a second coating consisting of a copper/Tin based alloy containing Pt and/or Pd and optionally Zn ad, to obtain hypoallergenic, zero Ni-releasing galvanized objects.
