When it comes to getting the job done in the world of pistons, understanding every aspect of their construction is key. For many people knowing if a piston is forged or cast is basic stuff but taking things a step further, understanding the metallic alloy that the piston is made from is not a topic they think about a lot.
Experienced engine builders know all of this stuff and the companies that supply them know it as well. 4032 is the most common alloy used in piston construction across the board. It is an alloy with a fairly large silicon content (more than 10%). It is good stuff and does the job well in many, many applications. 2618 is more malleable because it has very low silicon content and while slightly heavier, it is more forgiving in today’s growing number of boosted and power adder engines. Because of this trend, MAHLE Motorsport has opened the floodgates on 2618 alloy applications, adding some 200 more PowerPak kits to their already stacked lineup.
