ISO 428 was an International Organization for Standardization (ISO) standard fully entitled "Wrought Copper-Aluminium Alloys -- Chemical Composition And Forms of Wrought Products", specifying the allowable compositions of various copper-aluminum alloy specifications (see aluminium bronze). The standard, promulgated in 1983, was withdrawn in March 2000.
Following is a list of aluminium bronze wrought alloy compositions, by ISO 428 designations (proportional composition by weight; copper is the remainder by weight and is not listed):
