Effects of Ag and Riser System on the Porosity Content in A201 Aluminum Alloy Plate Castings

Name of activity：

Proceeding of The 11th Asian Foundry Congress

Keywords：A201 Aluminum Alloy Casting,Porosity Content,Ag contnet

Abstract： The different contents Ag (0.50,0.75,and 1.00 wt.%)of A201 aluminum alloy plate castings with systematic change of riser size, together with variation of thickness and length, were cast in silicate sands molds to investigate the relation to porosity content. The experimental results indicate that the porosity content in a long solidification range A201 aluminum alloy plate castings is governed not only on the riser size but also on the plate geometry and the content of Ag. Insufficient feeding of the castings and too much Ag may increase porosity content.
