Master alloy for white gold 9, 10, 14 and 18K. The formulation of SW 452 R is suitable for mechanical works. Thanks to its colour and mechanical characteristics, it is the first choice for solid chains and stamped items production. The colour obtained with SW 452 R is premium white (rhodium plating not necessary) in 9K, standard white (rhodium plating suggested) in 10 and 14K, and off white (rhodium plating needed) in 18K. The hardness of gold produced with SW 452 R can be increased with heat treatment only in 18K. Warning: This alloy contains Nickel.
