What is Hypereutectic?
Made upof Hypereutectic alloy... Hypereutectic alloy is a combination of aluminum and silicon
For applications involving a supercharger, turbocharger, or nitrous oxide, forged pistons are typically recommended due to their superior strength and ability to withstand higher pressures and temperatures. Hypereutectic pistons are more brittle and may not handle the stress from forced induction as effectively, while cast pistons are generally not suitable for high-performance applications. Forged pistons offer better durability and performance under extreme conditions, making them the ideal choice for boosted setups.

This is kind of a generic part number. The "L" usually means it's a forged piston, and the 2416 is the characteristics of that piston. TRW has an L2416-F30. Same piston, just made by TRW.

This is a type of high tech ultra light weight aluminum piston material for use in automotive engines. It has desirable strength and weight characteristics in comparison to cast pistons but lacks strength in comparison to Forged materials in piston manufacture.
The difference between a cast and forged piston is the way it is made. A cast piston is made by pouring or injecting molten aluminum into a mold and letting it cool. A forged piston is made by ramming a die into a hot but not quite molten ingot of aluminum in a mold under great pressure (20+ tons!) The extreme pressure created in the forging causes the metal to be denser and have a uniform grain, making it much stronger and less brittle. There is more to making forged pistons than just the different manufacturing process, they often start with a stronger alloy such as 4032 or 2618 aluminum. Cast pistons are high in silicon content, which makes them dimensionally stable under high temperatures, but brittle. Forgings have a low silicone content and thus "grow" (expand) more when hot, but offer much improved strength and resiliency .

How was this Forged? The sward was forged from pure metal.
