Technological properties

Name The value
Pressure treatment Suitable for rolling, drawing, sheet metal forming. Preserving the malleability of the metal, Nickel gives it the hardness.
Casting Suitable for all types of casting. Palladium raises the melting temperature of the gold alloy and dramatically changes its color. Nickel improves the casting properties of the alloy.
