Working with 3005-H16
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.
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.

3005-H16 — frequently asked
What is 3005-H16 used for?
3005-H16 is typically used for architectural siding, roofing sheet, composite panel skins, mobile home sheet, louvres and shutters and signage panels. In short: building sheet; stronger than 3003.
What is the yield strength of 3005-H16?
3005-H16 has a typical yield strength of 180 MPa (26.1 ksi) and a tensile strength of 200 MPa (29 ksi) — weaker than 54% of aluminum grades. Strength varies by condition: see the 17 listed tempers.
Is 3005-H16 easy to machine?
Not especially — machinability is rated fair (38/100, worse than 84% of aluminum grades). 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-H16 be welded?
Yes — weldability is rated very good (82/100). Readily GTAW/GMAW/resistance welded with ER4043 or ER5356 filler; HAZ anneals back to near-O strength, so design joints away from load peaks.
What surface finishes work on 3005-H16?

Can 3005-H16 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.
What is the maximum service temperature of 3005-H16?
3005-H16 is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in 3005-H16?
Yes — 3005-H16 is available for sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
