Melting temperatures of alloys

Reference table of melting points for gold, silver and platinum.

Melting temperature is a critical parameter for any goldsmith or melter. Working at a temperature that is too high degrades the metal (oxidation, coarse grains); too low, and the melting is incomplete.

Pure Metals: Gold (Au): 1,063°C · Silver (Ag): 961°C · Platinum (Pt): 1,768°C · Palladium (Pd): 1,555°C · Copper (Cu): 1,085°C · Zinc (Zn): 419°C

Gold Alloys: 18k Yellow: 879°C · 18k White (Pd): 954°C · 18k Rose: 904°C · 14k Yellow: 802°C · 9k: 855°C

Silver Alloys: 999 Silver: 961°C · 925 Silver: 893°C · 800 Silver: 841°C

Note: these values are the melting temperatures (onset). In practice, goldsmiths work 30–50°C above this to guarantee a fluid pour, but without exceeding the vaporization point of light alloys (zinc).
