Background of the Invention  Cast aluminum parts are widely used in the aerospace and automotive industries to reduce weight.
The differences between the two sets of data for the three metals are not systematic (α greater for Cu, less for Ag) and may be due to differences in sample purity since much larger low-temperature anomalies were found within each set for certain samples of Cu and Ag.
 In one aspect, the present invention is an aluminum casting alloy consisting essentially of: 4% - 9% Si; 0.1% - 0.7% Mg; less than or equal to 5% Zn; less than 0.15% Fe; less than 4% Cu; less than 0.3% Mn; less than 0.05% B; less than 0.15% Ti; and the remainder consisting essentially of aluminum.
 It is noted that the above percentages are in weight % (wt %).
