This International Standard specifies the chemical composition limits for aluminium casting alloys and mechanical properties of separately cast test bars for these alloys.
ISO 3522 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 7, Aluminium and cast aluminium alloys.
This fourth edition cancels and replaces the third edition (ISO 3522:2006), of which Table 1 has been technically revised concerning the chemical composition of AlSi9Cu3(Fe).
