A6061
ISO N (non-ferrous)Aluminum alloy (heat-treatable Al-Mg-Si, 6000 series). Standard: JIS H 4000 (sheet) / JIS H 4040 (bar) / JIS H 4100 (extruded shapes).
🌐International equivalents
“Close” means composition or properties are not exactly the same. Before substituting, check the values in each standard.
