Baienwei AlSi alloy is an ideal wear-resistant material for its high temperature strength,heat stability and high abrasion resistance.In recent years, AlSi alloy has a fast development in many applications,it has been widely used in automotive,motorcycles and military industry,for example,the wear-resistant components like pistons,cylinder liners and brake discs in tanks,motorcycles and cars.Using aluminum alloy engines is the important direction to replace cast iron engines and cast-in iron cylinder liner engines.
Nowadays,AlSi alloys are widely used in automotive industry.Many famous automotive companies have adopted AlSi alloys in automobile engines, such as Mercedes-Benz, Mazda,BMW,GM etc.Besides,AlSi alloys are also widely used in racing car field,such as F1 etc.
Baienwei has a large-scale production line of AlSi alloy automobile engines cylinder pistons and cylinder liners. Due to the low CTE,high wear-resistance and volume stability,hypereutectic silicon aluminum alloys have been regarded as the most ideal piston material in the world.
Main Features:
One of the advantges of AlSi alloys 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 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.
AlSi alloys have excellent thermal conductivity, when the piston is working,the surface temperature is low and there is little carbon deposit on surface.
AlSi alloy pistons could raise the fuel economy, have outstanding anti-vibration, noise damping and high thermal conductivity.
AlSi alloy pistons increase the power density of engines,which makes the overall properties much higher and output power be raised at least 15%.
