As an important technological parameter in indirect squeezing casting

the casting temperature has some effects on the hot tearing trend and mechanical properties of Al-5Cu alloy. The hot tearing rate and hot tearing coefficient obtained through changing casting temperatures indicate that proper increase of the casting temperature can be helpful to reducing hot tearing trend and to gaining the casting with impact structure. The experimental results show that for the alloy in squeezing casting at 750C

as-cast tensile strength is 273. 8 MPa

and T6 treated tensile strength is 450. 0 MPa

and T4 treated elongation is 17.6%.
