You face a metal\u2011profile decision and wonder: is 3004 aluminum alloy truly suitable for extrusion? The uncertainty can stall your next project.<\/p>\n

Yes \u2014 3004 alloy is a wrought aluminum alloy that can be extruded under the right conditions, though it is more common in sheet\/coil form and may not always be optimal for heavy structural extrusions.<\/strong> <\/p>\n

Let\u2019s walk through what 3004 offers, why engineers might select it, how to identify it, and whether it meets structural needs. This will help you decide if it fits your project.<\/p>\n

What properties define 3004 alloy extrusions?<\/h2>\n

Picture having a material that balances strength, formability and corrosion resistance \u2014 and you\u2019re asking: what makes 3004 tick? <\/p>\n

3004 is an Al\u2011Mn\u2011Mg wrought alloy (approx 1\u202f% Mn, ~1\u202f% Mg) offering moderate strength, excellent corrosion resistance and good formability; it is non\u2011heat\u2011treatable and strengthened by cold work.<\/strong><\/p>\n
