Абісинське золото

Залежність кольору сплаву Ag-Au-Cu від процентного вмісту, металів

Абісинське золото — стійкий до корозії мідний сплав, що імітує золото за кольором; містить 88% Cu, 11,5% Zn і 0,5% Au[1]. Додавання 0,5% Au сприяє тривалішому збереженню блиску без потемніння. За іншими джерелами можна знайти такі рецептури:

Назву сплав отримав через те, що вперше був створений в Абісинії (Ефіопії). Широко використовувався у XIX-му столітті для виготовлення ювелірних виробів (біжутерії).

Абісинське золото часто ототожнюють із «Talmigold» (або французьке золото), яке має подібний склад[6][7].
