Gold-plated metal refers to a base metal that has been coated with a thin layer of gold. This process is often achieved through electroplating, where an electric current is used to deposit gold onto the surface of the metal. The result is a shiny, attractive finish that resembles solid gold but is more affordable. The thickness of the gold layer can vary, affecting the durability and appearance of the item. Commonly used base metals include copper, silver, and brass. Gold-plated items are popular in jewelry and decorative objects, offering a luxurious look without the high cost of solid gold.
