It is a metal composed of 75% gold and 25% other metals. 750 of au750 refers to the gold content of 75%, and au is the chemical symbol of elemental gold. Compared with pure gold, au750 is richer in color, and has the advantages of resistance to deformation, wear resistance, and corrosion resistance.
au750 refers to 18k gold, and 750 in au750 refers to the metal content of 750 parts per thousand, which is 75% gold. And au refers to AU, which is the chemical symbol of elemental gold, so au750 is actually another way of saying that the gold content is 75% metal.
au750 is composed of 75% gold and 25% other metals, such as silver, nickel, copper and other metallic elements.
