To facilitate transport, storage and processing, pure metals and alloys are cast into ingots or bars, plates or sheets in various weights. There are gold, silver, platinum, steel, tin, nickel, iron, aluminum, copper, cobalt, lead and others for a host of applications. Metal scraps are also processed in this way, going through the same casting procedure so they can be reused to make new products. These ingots serve as primary materials or are alloyed with other metals to boost their properties, increasing strength and enhancing corrosion resistance that meet intended applications.
Aluminum ingots are commonly employed in the aerospace, electronics and home appliances industries, and cobalt ingots in magnets, mobile phones, batteries and medical equipment. Copper ingots are key inputs in the manufacture of electronic components, hardware and plumbing products, appliances, decorative items and handicrafts, and automotive radiators.
As for lead ingots, batteries are their biggest application, including those found in vehicles and emergency or backup power supplies, as well as underwater and communication cables, and bearings. Antimony ingots, meanwhile, are usually used to harden other metals because of their high resistance to corrosion and oxidation.
There are also hollow ingots, also called forged ingots, used as semifinished products for cylindrical forgings such as rings and shells.
