Aluminium Ingot

An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. In steel making. it is the first step among semi-finished casting . Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product. Non-metallic and semiconductor materials prepared in bulk form may also be referred to as ingots, particularly when cast by mold based methods. Also, metal ingots can be used as currency (with or without being processed into other shapes), or as a currency reserve, as with gold bars.
