The most known gold alloysare made with silver. The proportion between gold and silver changes the alloy color. In this way, there are yellow and white alloys and the last ones present different metallurgical properties. Alloys are influenced by the presence of other minerals or metals. The next table shows the melting point of m…See more on 911metallurgist
