3005 is an aluminum–manganese (Al–Mn) wrought alloy commonly used for corrosion-resistant, moderate-strength sheet products. Temper H14 indicates a strain-hardened condition with partial hardening (approximately 1/4 hard) achieved by cold working; it provides a balance of strength, formability and surface finish. The specified thicknesses (0.1, 0.2, 0.3, 0.5 mm) are typical for thin sheet applications such as decorative facings, cladding, light-weight housings, and heat-exchange fins.
features:
- Good corrosion resistance (atmospheric and many mildly corrosive environments)
- Good workability and moderate strength in H14 temper
- Excellent surface finish, suitable for coating and painting
- Good brazing and welding compatibility with common techniques
- Widely available in coils and cut-to-length sheets

Mechanical Properties (H14 temper, typical)
| Property | Unit | Typical Value |
|---|---|---|
| Tensile strength (Rm) | MPa | 115 – 165 |
| Yield strength (Rp0.2) | MPa | 70 – 120 |

Notes:
- Mechanical properties vary with thickness and degree of cold work. Thinner gauges and higher cold work typically yield higher strength and lower elongation.

Surface Finishes & Coatings
| Finish Type | Description / Use |
|---|---|
| Mill finish (bright) | Standard smooth surface; suitable for painting, anodizing and laminating. |
| Anodized | Improved corrosion resistance, appearance and surface hardness; common for architectural trims. |
| PVDF / Polyester paint | Long-term color retention and weatherability (architectural cladding). |
| Stucco-embossed | Reduced reflectivity, improved stiffness and appearance for facings and panels. |
| Protective film | Applied for transport/processing protection on thin gauges. |
Formability & Fabrication
Cold forming:
- 3005-H14 provides good formability for bending, light drawing and profiling; radius recommendations depend on thickness and desired springback.
- For 0.1–0.3 mm gauges, tight radius bending is possible, but watch for edge cracking if excessive deformation or poor tooling is used.
Welding & Joining:
- Compatible with MIG, TIG and resistance spot welding. Pre- and post-weld cleaning recommended for optimal strength and appearance.
- Brazing and soldering compatible; use appropriate fluxes for Al–Mn alloys.
Cutting & Punching:
- Laser cutting, shearing, slitting and fine punching are all suitable for these thin gauges. Burr formation and edge rollover must be considered for final assembly.
Surface treatment:
- Good adherence for adhesives, paints, and anodizing with standard pre-treatment (degreasing, etching, desmutting).
Corrosion Resistance
- Excellent resistance to atmospheric corrosion and mild chemical environments due to the absence of copper and presence of manganese.
- Not suitable for marine environments with direct saltwater spray without protective coatings — consider additional coatings or marine-specific alloys for long-term exposure.
- Good performance for architectural cladding, appliance panels, furniture, and indoor environments.
Typical Applications
| Application Area | Examples & Advantages |
|---|---|
| Architectural | Interior/exterior cladding panels, facades (with coatings), soffits, trims — lightweight, good appearance, easy fabrication. |
| Decorative & signage | Painted or anodized thin panels for signs, nameplates, decorative facings — good surface finish and paint adherence. |
| Consumer goods | Appliance panels, housings, lamp reflectors — corrosion resistance and aesthetic finish. |
| HVAC & heat exchange | Fins and thin elements — good thermal conductivity and formability. |
| Packaging & lamination | Specialty packaging components, laminates and foils where moderate strength and corrosion resistance are needed. |
| Automotive (non-structural) | Trim, interior panels — light-weight and corrosion resistant. |
| Electronics & electrical | Light enclosures, shield panels — conductive and thermally conductive where needed. |
Handling, Storage & Quality Assurance
Handling:
