Melting Temperatures of Gold Alloys
In many cases common "gold" is an alloy and the composition varies. Gold can be mixed with
silver, copper and other metals to form jewelry quality "gold".
"White gold" is formed with a combination of palladium or nickel and has a higher melting point
than many "yellow" golds. The various compositions of gold cause differing melting points. It is
advisable to use the melting point of the highest gold alloy included in your melt.
To achieve a clean melt, a gas atmosphere is preferred (not an oxygen atmosphere).
Additionally, graphite crucibles are used for yellow gold melts, but not white gold melts as the
nickel in the white gold alloy can interact poorly with the graphite and contaminate the melt.
Overheating the melt can cause damage to the alloys, so in order to achieve flow after
melting, do not exceed 100o F - 175o F above the melting point.
