Metal ingots are solid blocks of metal that are typically produced by casting molten metal into a mold. They serve as a raw material for various manufacturing processes, including forging, rolling, and machining. Common metals used for ingots include aluminum, copper, iron, and steel. Ingots can vary in size and shape, depending on the type of metal and the intended use. They are often used in industries such as construction, automotive, and aerospace, where they are transformed into finished products or components. The production of metal ingots is a crucial step in the metalworking supply chain.
