  Artificial limbs are made from numerous materials the socket or the area which is attached to the limb is usually made from a plastic (polypropylene). The actual leg is usually made out of a lightweight metal material like titanium or aluminium. Some new implants are being made out of a reinforced polymer known as carbon fibre.
