Baienwei hypereutectic piston aluminum are produced by spray forming process.

Compare to conventional pistons, hypereutectic pistons have many advantages:

• Raise the fuel economy, 

• Outstanding anti-vibration, noise damping,
  

• Excellent thermal conductivity,
  

• Increase the power density of engine,

• Reduce the weight of pistons and inertia force of reciprocating motion,

• Reduce the friction, high wear-resistant.
