A356/Al2O3/20p F vs A356/Al2O3/20p T5

Composite · A356/Al2O3/20p grade comparison

A356/Al2O3/20p F and A356/Al2O3/20p T5 are two grades of the same composite grade, A356/Al2O3/20p: F (as fabricated) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. A356/Al2O3/20p T5 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 125 MPa (18.1 ksi) for A356/Al2O3/20p F, about 64% more; tensile strength follows at 255 MPa (37 ksi) vs 190 MPa (27.6 ksi). In exchange, A356/Al2O3/20p F is the more ductile: elongation 1% versus 0.8% for A356/Al2O3/20p T5.
