Extra-hard partially annealed 3104 strip, close to H19 strength but with slightly better residual ductility for high-speed can-body and end stock.
What is 3104-H29?
3104-H29 is 3104 in the H29 temper — extra-hard partially annealed 3104 strip, close to H19 strength but with slightly better residual ductility for high-speed can-body and end stock. 3104-H29 has a yield strength of 260 MPa (37.7 ksi) and a tensile strength of 285 MPa (41.3 ksi) — stronger than 68% of aluminum grades. Elongation at break is 4% and the elastic modulus is 69 GPa (10 Msi). 3104-H29 has a density of 2.72 g/cm³ (0.0983 lb/in³), heavier than 57% of aluminum grades. It melts at 629°C (1,164 °F).

Working with 3104-H29
Is 3104 easy to machine?
Soft and gummy — use sharp polished-flute carbide, high rake, high speed and flood lubricant to avoid built-up edge; chip breaking is poor.
Can 3104 be welded?
Readily GTAW/GMAW welded with 4043 or 5356 filler and resistance-welded; the strain-hardened HAZ softens back toward O-temper strength.
Can 3104 be formed, bent or molded?
In O/H2x tempers it deep-draws superbly; H19 coil is engineered for draw-and-wall-ironing of can bodies with controlled earing (<3 %) — avoid tight bends across the rolling direction.
What surface finishes work on 3104?
Normally lacquered or coil-coated after chromate-free conversion pretreatment; anodizes protectively but with a grey/brown tone, and it takes paints and printing inks well.

What is 3104-H29 used for?
3104-H29 is typically used for beverage can bodies, can cap and closure stock, draw-and-ironed containers, aerosol containers, coil-coated container stock and deep-drawn housings. In short: can body sheet; beverage industry.
What is the yield strength of 3104-H29?
3104-H29 has a typical yield strength of 260 MPa (37.7 ksi) and a tensile strength of 285 MPa (41.3 ksi) — stronger than 68% of aluminum grades. Strength varies by condition: see the 21 listed tempers.
Is 3104-H29 easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 65% of aluminum grades). Soft and gummy — use sharp polished-flute carbide, high rake, high speed and flood lubricant to avoid built-up edge; chip breaking is poor.
Can 3104-H29 be welded?
Yes — weldability is rated very good (72/100). Readily GTAW/GMAW welded with 4043 or 5356 filler and resistance-welded; the strain-hardened HAZ softens back toward O-temper strength.
What surface finishes work on 3104-H29?
Normally lacquered or coil-coated after chromate-free conversion pretreatment; anodizes protectively but with a grey/brown tone, and it takes paints and printing inks well.
