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 The standard, promulgated in 1983, was withdrawn in March 2000.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

Alloy Aluminium Iron Nickel Manganese Zinc Arsenic
CuAl5 4.0% - 6.5% 0.5% max 0.8% max 0.5% max 0.5% max 0.4% max
CuAl8 7.0% - 9.0% 0.5% max 0.8% max 0.5% max 0.5% max
CuAl8Fe3 6.5% - 8.5% 1.5% - 3.5% 1.0% max 0.8% max 0.5% max
CuAl9Mn2 8.0% - 10.0% 1.5% max 0.8% max 1.5% - 3.0% 0.5% max
CuAl10Fe3 8.5% - 11.0% 2.0% - 4.0% 1.0% max 2.0% max 0.5% max
CuAl10Fe5Ni5 8.5% - 11.5% 2.0% - 6.0% 4.0% - 6.0% 2.0% max 0.5% max
