This paper discusses principles and variables involved in making high strength aluminum alloy castings, as well as practical means for controlling factors necessary for obtaining maximum available strength from them. With the necessary conditions attained, mechanical properties equivalent to those of corresponding wrought aluminum alloys can be achieved. Detailed description is give?x of a reduced pressure test proposed by Baker, in England, for indicating gas content of molten aluminum, and evidence of the great value of this test as a quality control tool is presented.
