What is 3005-H29?
3005-H29 is 3005 in the H29 temper — maximum-strength partially annealed 3005 strip, one step above H28, used for thin high-strength sheet and fin/shutter stock where formability is minimal. 3005-H29 has a yield strength of 240 MPa (34.8 ksi) and a tensile strength of 255 MPa (37 ksi) — stronger than 62% of aluminum grades. Elongation at break is 2% and the elastic modulus is 69 GPa (10 Msi). 3005-H29 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).

Working with 3005-H29
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-H29 — frequently asked
What is 3005-H29 used for?
3005-H29 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-H29?
3005-H29 has a typical yield strength of 240 MPa (34.8 ksi) and a tensile strength of 255 MPa (37 ksi) — stronger than 62% of aluminum grades. Strength varies by condition: see the 17 listed tempers.
Is 3005-H29 easy to machine?
Reasonably — machinability is rated fair (48/100, worse than 67% 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-H29 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-H29?

Can 3005-H29 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-H29?
3005-H29 is rated for continuous use to about 110°C (230 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
