The market demand for Aluminium billet, which is one of the most widely used aluminium product forms globally, is in constant rising. Billets are created directly through continuous casting or extrusion or indirectly through hot rolling an ingot or bloom. The billet is normally suitable for alloyed aluminium.
The foundry combines raw aluminium with other metals and minerals to form different alloys and grades of aluminium. Once the materials are combined, smelted, and all impurities removed, billets are formed by placing the aluminium in a form under intense pressure. The high pressure removes all air and gas bubbles, aligns the molecules forming a solid block of aluminium that is high in density without any visible grains or defects. The size and shape of the billet depends on the part, which is to be carved out of it.
Billets can be further processed to make bar stock and wire. So, aluminium alloys are cast in billets to make automotive, aerospace parts and also for other applications like packaging, construction, electrical and electronics. Aluminium billets can be produced out of primary as well as secondary aluminium.
