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 The standard, promulgated in 1983, was withdrawn in March 2000.
