Car wheels are cast in aluminium which is strong and light.  Low pressure die casting is the process that is normally used, and millions of die cast wheels are made every year.

You can also see a brake disc here, which is also a casting – this disc is made by pouring molten grey cast iron into a sand mould.  Highly automated, high volume greensand casting is the process used and the sand for the mould is used over and over again. Castings are used to keep us safe on the roads.

You might also be able to spot the brake caliper which is also an iron casting.  Castings are everywhere!
