out of aluminium copper calcium and 3 the in estonia
Permanent expansion accompanies precipitation out of solution of silicon, magnesium and copper; the amount varies but maybe as high as 0.15%. Thermal conductivity is of the order of 1.2-1.6 x 10 -2 W/m/K, the lower values being for the alloys cast in metallic molds or heat treated to retain silicon, copper or magnesium in solution.

Aluminum (Al) and water - Lenntech
The amount of aluminum in seawater varies between approximately 0.013 and 5 ppb. The Atlantic Ocean is known to contain more aluminum than the Pacific Ocean. River water generally contains about 400 ppb of aluminum. Aluminum mainly occurs as Al 3+ (aq) under acidic conditions, and as Al(OH) 4-(aq) under neutral to alkalic conditions.
