Slightly strain hardened | Mill-standard 'soft' coil condition where a small amount of straightening/levelling work is unavoidable; formability essentially as O. | 50 | 110 | 20 | 30 HB | 53 % IACS |
Strain hardened and partially annealed, quarter hard | Stabilized/partially annealed equivalent of H12 — slightly lower strength but noticeably better ductility and bendability. | 90 | 120 | 11 | 34 HB | 52 % IACS |
Strain hardened, quarter hard | Light cold work for flat panels that still need moderate bending; good compromise of stiffness in service and formability. | 105 | 125 | 9 | 36 HB | 52 % IACS |
Strain hardened and partially annealed, half hard | Most popular formable half-hard temper: H14-level strength with better elongation for bent brackets, trim and enclosures. | 110 | 135 | 8 | 39 HB | 52 % IACS |

Working with 5110A-H14
Is 5110A easy to machine?
Machines easily but gummily — use sharp polished high-rake carbide, high speed, generous lubrication and chip evacuation; the H1x/H2x tempers give cleaner chips than O.
Can 5110A be welded?
Readily GTAW/GMAW/resistance welded with 5356 or 4043 filler; the HAZ softens back toward O strength, so design joints for annealed properties.
Can 5110A be formed, bent or molded?
Excellent cold formability in O/H22/H24 (deep drawing, hemming, roll forming); minimum bend radii grow quickly in H16–H19, and interanneal at 340–410 °C if severe redrawing is needed.
What surface finishes work on 5110A?
Takes clear, bright and dyed anodizing very well due to low Mg/Si; also chromate/Ti-Zr conversion coats and powder paint. Polishes to a good specular finish; avoid alkaline cleaners that etch the surface.

5110A-H14 — frequently asked
What is 5110A-H14 used for?
5110A-H14 is typically used for general sheet fabrication, light structural brackets and gussets, enclosures and chassis panels, anodized trim and decorative panels, roofing and cladding sheet and appliance and equipment panels. In short: best-anodizing 5000-series here; low-Mg formable sheet; high conductivity for 5000 series.
What is the yield strength of 5110A-H14?
5110A-H14 has a typical yield strength of 125 MPa (18.1 ksi) and a tensile strength of 140 MPa (20.3 ksi) — weaker than 75% of aluminum grades. Strength varies by condition: see the 11 listed tempers.
Is 5110A-H14 easy to machine?
Not especially — machinability is rated fair (40/100, worse than 81% of aluminum grades). Machines easily but gummily — use sharp polished high-rake carbide, high speed, generous lubrication and chip evacuation; the H1x/H2x tempers give cleaner chips than O.
Can 5110A-H14 be welded?
Yes — weldability is rated excellent (88/100). Readily GTAW/GMAW/resistance welded with 5356 or 4043 filler; the HAZ softens back toward O strength, so design joints for annealed properties.
What surface finishes work on 5110A-H14?
Takes clear, bright and dyed anodizing very well due to low Mg/Si; also chromate/Ti-Zr conversion coats and powder paint. Polishes to a good specular finish; avoid alkaline cleaners that etch the surface.
Can 5110A-H14 be formed, bent or molded?
Excellent cold formability in O/H22/H24 (deep drawing, hemming, roll forming); minimum bend radii grow quickly in H16–H19, and interanneal at 340–410 °C if severe redrawing is needed.
What is the maximum service temperature of 5110A-H14?
5110A-H14 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 5110A-H14 and 5110A-O?
H14 is the default condition — the default general-purpose stocked sheet temper: enough strength for panels and light structures while still bending to moderate radii. O: pick for deep drawing, stretch forming, tight-radius bending or where maximum ductility and best anodized uniformity matter. Yield strength is 125 MPa in H14 versus 40 MPa in O.
