This document provides information on various non-ferrous alloys, including their compositions and properties. It discusses aluminum alloys such as duraluminum and corrosion resistant alloys. Copper alloys described include brasses, bronzes, and cupronickels. Other alloys covered are magnesium, zinc, lead, and titanium alloys. For each type of alloy, common compositions are provided along with properties like strength, ductility, and applications.
