What is 3104-H19?
3104-H19 is 3104 in the H19 temper — the standard beverage-can body-stock temper: highest as-rolled strength with just enough ductility for draw-and-wall-iron. 3104-H19 has a yield strength of 275 MPa (39.9 ksi) and a tensile strength of 295 MPa (42.8 ksi) — stronger than 70% of aluminum grades. Elongation at break is 3% and the elastic modulus is 69 GPa (10 Msi). 3104-H19 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-H19
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-H19 used for?
3104-H19 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-H19?
3104-H19 has a typical yield strength of 275 MPa (39.9 ksi) and a tensile strength of 295 MPa (42.8 ksi) — stronger than 70% of aluminum grades. Strength varies by condition: see the 21 listed tempers.
Is 3104-H19 easy to machine?
Not especially — machinability is rated fair (35/100, worse than 86% 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-H19 be welded?
Yes — weldability is rated excellent (85/100). 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-H19?
