Description

The color gold jewelry alloy AuAg30Cu11.5, in the literature also 585Au-300Ag-115Cu, corresponds to a fineness of 585/1000 Au, also with 14 carats (24 carats is 1000/1000 Au = fine gold). The alloy (designation: 585/300) has a pale yellow color and is used for chains and braids, for precision castings as well as for driving and deep-drawing work.
