Abstract

White solder alloys for dental and jewellery parts having working temperatures of about 1000 DEG C contain 38 to 70% by weight of gold, 6 to 20% by weight of palladium, 8 to 40% by weight of silver, 1 to 6% by weight of iron and/or cobalt, 0 to 10% by weight of copper, 0-5% by weight each of indium, zinc and tin, 0 to 4% by weight each of gallium and germanium, ruthenium and/or rhenium, it being necessary for the sum of the contents of tin, zinc, indium, gallium and germanium to be between 1 and 5% by weight.
