Zusammenfassung:The invention belongs to metal material field; it refers to an aluminium base composite material in piston and the producing method. It is made up of base alloy and enhanced phase, the weight p0ercentage of each component in base alloy is silicon 9-16%, copper 0.5-2.5 nickel 0.5-2.0, magnesium 0.2-1.2, titanium 0.2-2.0, the other is aluminium; the enhanced phase is Al2O3 and TiC particles. The producing method is: confects base alloy, and it is compounded; then carries on degenerative process, fining process, rough moulding, T6 heat processing.
