AA 3005 · UNS A93005 · EN AlMn1Mg0.5, AW-3005
3005 is a non-heat-treatable Al-Mn alloy of the 3000-series family that adds about 0.4 % Mg to the manganese base of 3003, raising strength roughly 20–25 % by solid-solution strengthening while keeping good formability and atmospheric corrosion resistance.

What is 3005?
3005 is a non-heat-treatable Al-Mn alloy of the 3000-series family that adds about 0.4 % Mg to the manganese base of 3003, raising strength roughly 20–25 % by solid-solution strengthening while keeping good formability and atmospheric corrosion resistance. It is supplied mainly as sheet, strip and pre-painted coil for architectural roofing and siding, composite-panel core, louvres, utensils and signage. Strength is available only through cold work, strain-hardened tempers recover and soften above 150 °C, and the magnesium makes vacuum and flame brazing slightly less easy than with 3003, which is the nearest lower-strength alternative. 3005 has a density of 2.73 g/cm³ (0.0986 lb/in³), heavier than 61% of aluminum grades. It melts at 630°C (1,166 °F). 3005 has a yield strength of 155 MPa (22.5 ksi) and a tensile strength of 175 MPa (25.4 ksi) — weaker than 63% of aluminum grades. Elongation at break is 5% and the elastic modulus is 69 GPa (10 Msi).

Working with 3005
Is 3005 easy to machine?
Soft and gummy — use polished high-rake carbide, high speed, generous coolant/lubricant to avoid built-up edge; expect burrs on thin sheet.
Can 3005 be welded?
Readily GTAW/GMAW/resistance welded with ER4043 or ER5356 filler; HAZ anneals back to near-O strength, so design joints away from load peaks.
Can 3005 be formed, bent or molded?
Excellent roll forming, bending and stamping in O/H2x tempers; bend across the rolling direction and use larger radii for H16 and harder.
Manufacturability
The process limits FabDigit applies to 3005. Every 3005 part is priced by an engineer; design inside these and the quote comes back without a redesign loop.

What surface finishes work on 3005?
Prime substrate for coil coating (PE/PVDF) and chemical conversion; clear anodizing is uniform but slightly grey, and brazing/flux processes need care because of the Mg content.
