rovements in Gold Alloys, of which the ollowing is a specification. This invention relates to particularly alloys and more object to improve the physical characteristics as well as the color thereof.
While many previous alloys of this type have been proposed, some are not entirely 1 satisfactory for one or more of several reasons such as color, malleability, hardness, ductility etc., and it is desirable to increase the facility of reworking as far as possible, as annealing is neither satisfactory nor effective in all'cases. Many of the allo s heretofore proposed are open to serious 0 jection because they cannot be readily reworked which is a requisite especially in the manufacture of jewelry rings and similar articles.
According to this invention, I have discovered an alloy in which previous objec tions are overcome and which furnishes the desired facility for reworking and yet having the desired color and hardness. I have discovered that small quantities of palladiumproduce the desired result and especi to precious metal alloys, com-. 10- monly called white gold, and has for its GOLD ALLOY.
