ABSTRACT:
The present invention provides a thixoformable Al alloy composites wherein Si is added to ASTM 2000 series aluminum alloy so that the total Si content thereof may be 1-5 at. % and also a manufacturing method of thixoformable Al alloy composites comprising: obtaining a matrix of the composite containing 1-5 at. % of the total Si content by adding Si to ASTM 2000 series aluminum alloy; holding the matrix in the temperature range of 560-610.degree. C. to obtain a liquid fraction of 40-70% and thereafter performing a thixoforming process.
