Alloys For Karat Gold
The following alloy table indicates recommended karat usages, alloy melting temperatures, and resulting karat gold melting temperatures.
Yellow and Green Alloys
The yellow and green alloys are listed in order of increasing silver content. The silver content is very influential on the color of the karat gold produced; low silver content yields reddish colors and higher levels yield greener colors.
The white alloys are listed in order of increasing nickel content. The alloy’s nickel content is most influential in resulting karat gold properties and color. As the nickel content increases, the whiteness, strength, and hardness increase. The alloys listed offer the optimum balance between color and workability.
Nickel Free White Alloys are available for 10K, 14K, and 18K, and conform to European Nickel Standards, are non-allergenic, and avoid the risk of stress corrosion.
Pink (Rose) Alloys
Alloys are also available with silicon and boron deoxidizers which produce brighter, smoother castings with less porosity.
Deoxidized alloys are only recommended for casting applications.
Stone In Casting
A number of our alloys are suitable for casting with stones.
High quality enameling is achieved with the following zinc-free alloys: #340, #208, #216, #120, #219, and #355.
Age Hardening Alloys
For pins, snaps, posts, clasps, locks, and other manufacturing applications requiring hardness and higher tensile strength: #208, #216, and #202.
