Abstract
A piston of a die-casting apparatus comprises: a piston head fabricated of a first material; an elongate, inner carrier coupled to the piston head; a generally annular body seated on the carrier adjacent the piston head; and a wear ring disposed on the piston head, the wear ring being fabricated of a second material. The first material has a higher toughness and a lower hardness than the second material.
