2mm thick 3003 6061 5005 5052 5754 5083 Alloy Aluminum Strip
When it comes to selecting aluminum strips at a medium thickness of around 2mm, the unique properties and optimal uses of various alloys can empower manufacturers, fabricators, and designers to make informed choices. Each alloy grade—3003, 6061, 5005, 5052, 5754, and 5083—brings a distinct set of mechanical properties, chemical compositions, and temper options.
Why 2mm Thickness?
A 2mm aluminum strip thickness sits in a valuable range for applications requiring a balance of flexibility and strength, as well as corrosion resistance. It is neither too thin as in foil-like layers nor too thick to impair bendability or conductivity. This medium-thickness strip is widely utilized in automotive paneling, architectural cladding, marine sheathing, and precision components in electrical and packaging industries.
Alloy Breakdown: Composition & Properties
| Alloy | Major Alloying Elements | Typical Temper | Yield Strength (MPa) | Elongation (%) | Corrosion Resistance | Applications |
|---|---|---|---|---|---|---|
| 3003 | Al-Mn (1.0-1.5%) | H14 / H18 | ~115 | 12-22 | Good | Decorative trim, roofing, cooking utensils |
| 6061 | Al-Mg-Si | T6, T651 | ~275 | 8-12 | Moderate | Structural frames, aerospace, transport |
| 5005 | Al-Mg (0.8-1.2%) | H14 | ~140 | 8-10 | Excellent | Architectural panels, indoor/outdoor signage |
| 5052 | Al-Mg (2.5%) | H34 / H32 | 190-230 | 10-17 | Excellent, saltwater resistance | Marine, fuel tanks, roofing |
| 5754 | Al-Mg (3%) | H22 / H24 | ~200 | 8-18 | Very good | Automotive bodywork, ship building |
| 5083 | Al-Mg (4-5%) with Mn (0.4%) | H111 | ~215 | 12-15 | Superior, marine-grade | Shipbuilding, pressure vessels, cryogenics |
Tempering and Standards
For a consistent supply of 2mm aluminum strips, suppliers adhere to international standards such as ASTM B209 (Aluminum and Aluminum-Alloy Sheet and Plate), EN 573-3 (Chemical Composition), and EN 515 / AMS 4015 (Temper Designations). Each temper alteration adjusts the mechanical and forming properties:
- H14 (Half Hard): Moderate strength with improved formability.
- H18 (Full Hard): Maximum strength achievable by strain hardening.
- T6 / T651: Solution heat treated and artificially aged for maximum strength in 6061.
- H32 / H34: Strain hardened and stabilized, common in marine grade alloys like 5052.
These temper options allow for customization depending on whether the 2mm strip requires bending, moderate forming, or high load-bearing capacities.
The use of these alloys within a 2mm thickness opens doors to applications unconstrained by either weakness or unwieldy stiffness. For instance:
3003 Alloy: At 2mm thick, it excels in architectural decorative features where malleability and aesthetic surface treatments (like anodizing or painting) matter most.
6061 Alloy: Offering this moderate 2mm thickness in T6 temper positions it perfectly for aerospace-grade brackets and frameworks where weight savings cannot compromise strength.
5005 Alloy: Used for indoors/outdoors signage that profits from the corrosion resistance and excellent paintability at this thickness, ensuring long life with low maintenance.
5052 & 5754 Alloys: These marine-grade alloys in 2mm strips provide reliable saltwater corrosion resistance and are often deployed in boat hull reinforcements, mast cladding, and fuel storage containers demanding toughness and durability.
5083 Alloy: At 2mm, it strikes a balance between strength, corrosion resistance, and formability; for example, in shipbuilding panels and specialized cryogenic container lining where material failures would be catastrophic.
Practical Considerations in Procurement and Fabrication
When sourcing 2mm aluminum strips of these alloys:
- Surface finish requirements (e.g., mill finish, brushed, mirror polished) depend on end-use visual and functional needs.
- Material certifications confirming compliance with ASTM, EN, or AMS standards prevent downstream risks.
- Controlling dimensional tolerances at 2mm thickness will influence joint fits in fabrication.
Fabricators will appreciate characteristics such as the good weldability in 5052 and 5754, while 6061 offers excellent machinability for complex components.
