Ingots are solid blocks of metal, typically produced by casting molten metal into a mold. They are often used as a raw material for further processing in manufacturing and metalworking. Common metals made into ingots include gold, silver, copper, and aluminum. The shape and size of ingots can vary, but they are usually rectangular or square. Once cooled and solidified, ingots can be melted down again or shaped into other products, such as sheets, bars, or wires. This versatility makes ingots an essential component in industries like construction, electronics, and jewelry, where high-quality metals are required.
