Product Details

High performance hypereutectic aluminum-silicon-AlSix(x=18,25,and 35 wt%) alloy products for automotive application,such as the AlSi alloy pistons.


Key benefits of Al-Si alloy pistons:

● One of the advantges of aluminum-silicon(Si-Al) alloy is low density,only 1/3 the weight of casting iron and steel iron,which will reduce the weight of pistons and inertia force of reciprocating motion.

●  AlSi alloy high performance pistons have less side pressure and impact to cylinder wall,which will reduce the friction and abrasion among piston set,cylinder wall and piston pins.

●  Improve the fuel economy, have outstanding anti-vibration as well as noise damping and high thermal conductivity.

 Al-Si alloy piston increases the power density of engines,which makes the overall properties much higher and output power be raised at least 15%
