2024 Chemical Element Composition Content (%)

Component	Fe	Si	Mn	Cr	Cu	Ti	Zn	Mg	Other Individual	Other Total	More
Minimum Value	-	-	0.3	-	3.8	-	-	1.2	-	-	Al: Remainder
Maximum Value	0.5	0.5	0.9	0.1	4.9	0.15	0.25	1.8	0.05	0.15	Al: Remainder

"Other individual elements or other totals": The chemical composition includes elements not specified in the table. Analysis should only be conducted if these elements are suspected to be present, or if routine analysis suggests that their content may exceed the prescribed limits.

① With agreement between the purchaser and supplier, Zr+Ti may 0.2% max.
② The alloy group is AL4.
