A copper ingot is a solid block of copper metal, typically produced by melting and casting copper ore or scrap. It serves as a primary form for further processing, such as rolling, forging, or alloying. Copper ingots are essential in various industries, including electrical, construction, and manufacturing, due to copper's excellent conductivity and malleability. Copper ingots are often produced in foundries and can vary in size and weight. They are usually marked with information about their purity and origin. The use of copper ingots dates back thousands of years, making them a significant part of human history and metallurgy, particularly in the development of tools and currency in ancient civilizations like Mesopotamia.
