gold alloy

**gold alloy**
A gold alloy is a material made by combining pure gold with other metals to enhance its strength, durability, and color. Common metals used in gold alloys include copper, silver, nickel, and zinc. These alloys are widely used in jewelry, electronics, and dental applications to provide a balance between the luxurious appeal of gold and practical functionality. Different ratios of gold to alloy metals result in various karat values and hues, such as rose gold, white gold, and green gold.
