Title:
GOLDEN Pd-In ALLOYS
Document Type and Number:
WIPO Patent Application WO/2008/053559
Kind Code:
A1
Abstract:
Conventional gold and gold alloys are expensive, while copper-zinc alloys are poor in corrosion resistance though they are inexpensive. Further, sintered titanium nitride alloy has the disadvantage of necessitating special equipment and technique and so on. The invention has been accomplished on the basis of a finding that alloys consisting of palladium (Pd) and indium (In) sparkle with gold though both palladium and indium are white metals. Golden Pd-In alloys according to the invention are golden and have advantages in that they are more inexpensive than gold and gold alloys and excellent in corrosion resistance and that no special equipment is necessary in producing the Pd-In alloys.
