ABSTRACT:
A palladium-based alloy is disclosed having a composition consisting essentially of nickel in the range of about 3 to about 30 atom percent, silicon in the range of about 15 to about 20 atom percent, the balance being palladium plus incidental impurities. The alloys of the present invention are particularly suited for joining stainless steels employed in orthodontic devices at brazing temperatures less than about 900.degree. C. The alloys are typically produced in the form of a foil having a thickness of at least about 150 .mu.m.
