The Phase Transition Bottleneck: Why Do Thick Aluminum Die Castings Fail Under Pressure? Reference Standard: ASTM B108/B108M – Standard Specification for Aluminum-Alloy Permanent Mold Castings Short Answer Internal porosity and shrinkage in aluminum die castings occur when extreme variations in wall thickness—such as a jump from 4.154mm to 53.312mm—cause erratic cooling rates. This differential cooling … Weiterlesen
