A Study in the Mechanical Properties Changes of Gold Alloy according Precious Metals Processing

The rise of gold prices and consumers diverse needs and decorative precious metal jewelry industry in terms of the actual effects could be saved, the development of multi-colored gold alloy is required. Also, gold is too soft and workability off Au, Ag, copper (Cu) alloy system with three kinds of 18K gold alloy elements of different colors changing and examined the changes in mechanical properties. Therefore, this alloy workability crush bending, stamping, cutting, rolling, drawing, etc. most of the techniques of jewelry that is very suitable for machining and welding torch, welding can be easily and can be found.
