What is the best material for piston rings ?

A popular material used for piston rings is cast iron, often referred to as grey iron. The biggest advantage in using cast iron to manufacture pistons rings is that it will not gall or scuff the cylinder bore. And as long as the cast iron ring is sufficient in size, it will provide adequate seal.
