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 The standard, promulgated in 1983, was withdrawn in March 2000.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