5005 and 5052 aluminum sheet/plate/coil are two of the most widely specified non-heat-treatable (strain-hardenable) aluminum-magnesium alloys used for corrosion-resistant, formable, and weldable products. They share a similar manufacturing footprint-rolled sheet, plate, and coil-yet they serve slightly different performance goals: 5005 is favored for appearance-critical anodized surfaces and general sheet metal, while 5052 is chosen when strength and marine-grade corrosion resistance are required.
Product forms
- Sheet: typically thin-to-medium gauges for fabrication, forming, enclosures, architectural panels
- Plate: thicker gauges for structural parts, bases, tooling plates, marine and industrial components
- Coil: continuous roll for stamping, roll forming, cladding, and high-throughput production
strengths
- Excellent corrosion resistance (especially 5052)
- Strong forming performance in O/H32 tempers
- High weldability using common aluminum fillers
- Good surface finish options (mill finish, brushed, coated, anodized-5005 excels for anodizing)
2) Alloy Positioning: 5005 vs 5052 (Quick Selection Guide)
| Category | 5005 | 5052 |
|---|---|---|
| Primary alloying | Mg (lower) | Mg (higher) + Cr |
| Typical priority | Surface appearance, anodizing uniformity, general sheet | Higher strength, marine/chemical corrosion resistance |
| Formability | Very good | Very good (slightly higher strength may require higher force) |
| Weldability | Excellent | Excellent |
| Anodizing | Excellent; color match & uniformity | Good (can be less uniform vs 5005 in some decorative finishes) |
| Corrosion resistance | Very good (general) | Excellent (marine/industrial) |
| Relative strength | Moderate | Higher |
| Typical end use | Architectural trim, appliance panels, signage | Boat hull parts, tanks, pressure covers, truck bodies |
3) Chemical Composition (Typical Standards Reference)
Note: Actual limits vary by standard (ASTM B209 / EN / JIS). The table below reflects common composition ranges used in commercial practice.
| Alloy | Mg (%) | Mn (%) | Cr (%) | Si (%) | Fe (%) | Cu (%) | Zn (%) | Ti (%) | Al |
|---|---|---|---|---|---|---|---|---|---|
| 5005 | 0.5–1.1 | ≤0.20 | ≤0.10 | ≤0.30 | ≤0.70 | ≤0.20 | ≤0.25 | ≤0.20 | Balance |
| 5052 | 2.2–2.8 | ≤0.10 | 0.15–0.35 | ≤0.25 | ≤0.40 | ≤0.10 | ≤0.10 | ≤0.15 | Balance |
What the chemistry means
- More Mg (5052) → higher strength and improved resistance in saline/industrial atmospheres.
- Controlled impurities (both alloys) → better formability and more stable corrosion behavior.
- Cr in 5052 → improves resistance to stress corrosion and helps stabilize properties.
4) Mechanical & Physical Performance
4.1 Typical Mechanical Properties by Temper
Values shown are representative for sheet/coil; plate values may differ with thickness. Always confirm mill test certificate (MTC) for guaranteed minima.
| Alloy / Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Notes |
|---|---|---|---|---|
| 5005-O | 110–145 | 35–55 | 20–30 | Maximum formability, best for deep drawing |
| 5005-H34 | 170–215 | 140–175 | 6–12 | Stiffer panels, improved dent resistance |
| 5052-O | 170–210 | 65–95 | 18–28 | Good formability with higher baseline strength |
| 5052-H32 | 210–260 | 160–200 | 10–16 | Common "workhorse" temper for marine & tanks |
| 5052-H34 | 230–290 | 180–230 | 8–14 | Higher strength, slightly reduced formability |

6) Performance Highlights (Why These Alloys Sell)
Corrosion Resistance You Can Rely On
- 5052 is a frequent choice for saltwater exposure, splash zones, and chemical-laden environments due to higher Mg content and excellent resistance to pitting in many service conditions.
- 5005 performs strongly in general atmospheric exposure and indoor/outdoor architectural use.
Formability and Fabrication Efficiency
Both alloys can be:
- bent, roll-formed, stamped, and deep-drawn (best in O and H32)
- welded by MIG/TIG with common fillers (selection depends on design and corrosion requirements)
Practical note: tighter bend radii are easier in O temper, while H32/H34 improves stiffness and dent resistance for panels.
Surface Quality and Finishing
- 5005 is widely recognized for excellent anodizing response, often preferred when consistent cosmetic appearance is required (architectural trims, decorative panels).
- Both alloys accept painting and powder coating well when properly pretreated.
