Background
Brasses are alloys of copper and zinc. They may also contain small amounts of other alloying elements to impart advantageous properties. Brasses have high corrosion resistance and high tensile strength. They are also suited to hot forging. Free machining grades of brass set the standard for machining, by which other ...

Chemical specifications for zinc casting alloys are given in ASTM B86 for No. 2, No. 3, No. 5 and No. 7 alloys and ASTM B791 for ZA-8, ZA-12 and ZA-27.
Alloys covered by B86 are hypo-eutectic (i.e. they contain less aluminum than the eutectic chemistry of 5% Al) with a composition ...
