| Abstract: | The fluidity of A319, A356 and A413 alloys has been measured using a sand-cast spiral in the 700°C to 750°C temperature range. Modification by either sodium or strontium has no detectable effect on the fluidity and does not change the temperature dependence of fluidity within this temperature range. Measurements at 745°C indicate that sodium levels up to 0.037 wt% or strontium levels up to 0.024 wt% have no effect on the fluidity of sand-cast A356 alloy. |
