More About Watercraft Stage 1 Top End Piston kits Kawasaki, Polaris, Sea Doo, Yamaha and Tigershark
A hypereutectic piston is an internal combustion engine piston cast using a hypereutectic alloy–that is, a metallic alloy which has a composition beyond the eutectic point. Hypereutectic pistons are made of an aluminum alloy which has much more silicon present than is soluble in aluminum at the operating temperature.
