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.

Yellow Alloys

   GHS SDS

Green Alloys

   GHS SDS

White Alloys

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.

   GHS SDS

Pink (Rose) Alloys

   GHS SDS

Casting

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.

Enamel Alloys

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.
