Main Features:
The good compatibility of thermophysical properties between silicon aluminum alloy cylinder sleeves and aluminum alloy pistons could realize “no clearance cylinder”and “all-aluminum engine”,which will reduce the risk to avoid the failure of piston thermal etching“burn the top”,
”cylinder score”and”cylinder sticking”.Silicon aluminum alloy has been the main material of new type automobile cylinder sleeves.
The preparative technique of AlSi alloy cylinder sleeves: alloy composition analysis ,intermediate frequency furnace smelting,spray forming,
extrusion tube,heat treatment,NDT,forming process of cylinder sleeves, test. We adopts the spray forming technology to raise the overall
properties of alloy, which makes AlSi alloy cylinder sleeves have more technical advantages and competitiveness.

AlSi alloy cylinder sleeves could lower oil consumption,having properties of anti-vibration,noise damping and high thermal conductivity.

The weight of AlSi alloy cylinder sleeves is much lighter. Because of the low density of AlSi alloy,in automotive industry,1 kg AlSi alloy could replace 3 kg castings.

The application of AlSi alloy cylinder sleeves increases the power density of engines,which makes the overall properties much higher and output power be raised at least 15%.

AlSi alloy cylinder sleeves have excellent friction wearing properties.Silicon particles in silicon aluminum alloy has the functions of wearing resistance and auto-lubrication.
