How is gold made? - UCSB Science Line

One karat is 1/24 part (by weight) pure gold, so pure gold is 24 karats. Many products use various gold alloys for various reasons, but most do because the alloys are cheaper (usually silver, copper, zinc, nickel, etc. are mixed in), but sometimes gold is alloyed to make it a stronger and less malleable material. Answer 3:

Gold and Gold Alloys :: Total Materia Article

Gold is yellow and copper is red, the only two colored pure metals. All other metals are white or grey in color. Adding copper to gold makes it redder and adding silver, zinc and any other metal makes gold paler. Thus, we can understand that lower carat golds, because we can add more alloying metals, can have a wider range of colors than the ...
