Astm 3003 3004 H111 1mm thick 4x8 Aluminium Sheet
When it comes to versatile and reliable aluminum sheets for both industrial and commercial applications, the ASTM 3003/3004 H111 1mm thick 4x8 Aluminium Sheet stands out as a preferred choice. This specific grade and temper offer unique advantages in performance, workability, and durability.
ASTM 3003 and 3004 Aluminum Alloys
The 3000 series aluminum alloys primarily belong to the Mn-group, known for excellent corrosion resistance, moderate strength, and superior workability. Within this series, ASTM 3003 and 3004 are two widely-utilized variants exhibiting close, yet purposeful differences:
- ASTM 3003: Containing approximately 1.0% manganese, this alloy improves strength significantly beyond 1100 alloys without compromising ductility and corrosion resistance.
- ASTM 3004: A subtle evolution of 3003, it includes slightly higher manganese and additional alloying elements to enhance strength and surface finish adaptability.
Temper Designation: What Does H111 Mean?
Tempering in aluminum designates treatment or processes aimed at providing specific mechanical properties while controlling formability and hardness levels.
- H1xx series designates strain-hardened tempers without subsequent thermal treatment.
- H111, specifically, means the alloy has been cold worked to “not fully hard” temper.
The H111 temper imparts a good balance by offering improved tensile strength while maintaining optimum ductility. For a 1mm thickness Sheet in H111 condition, the metal remains highly workable—which is vital for forming processes such as bending, folding, and stamping required in construction, roofing, and signage manufacturing.
Sheet Size and Thickness: Why 1mm Thick, 4’ x 8’ Sheet Dimension?
- Thickness (1mm): Striking a middle-ground between flexibility and strength; thin enough for detailed fabrication but thick enough to ensure form integrity and dimensional stability.
- Sheet Dimension (4 feet by 8 feet, or 1220mm x 2440mm): The standardized size favours manufacturing efficiency, ease of transport, and compatibility with most cutting and machining equipment typical in the aluminum sheet market.
Implementation Standards Governing ASTM 3003/3004 H111 Aluminium Sheets
The production and procurement of aluminum sheets are rigorously controlled under several standards to assure consistent quality and mechanical integrity:
- ASTM B209 – The Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate lays down the mechanical properties, tolerances, marking, and permissible variability for jobs.
- ASTM B221 – In some contexts, this is applied for rolled and extruded shapes within comparable alloy series.
- National or regional standards (such as AMS , ISO ) might additionally apply depending on use case and segment.
Chemical Composition for ASTM 3003 and 3004 (Typical wt %)
| Element | 3003 (%) | 3004 (%) |
|---|---|---|
| Aluminum | Balance | Balance |
| Manganese | 1.0 – 1.5 | 1.2 – 1.8 |
| Copper | 0.05 – 0.20 | Up to 0.20 |
| Silicon | ≤ 0.6 | ≤ 0.5 |
| Iron | ≤ 0.7 | ≤ 0.7 |
| Zinc | ≤ 0.10 | ≤ 0.10 |
| Titanium | ≤ 0.15 | ≤ 0.15 |
| Others* | ≤ 0.05 | ≤ 0.05 |
(*) Others include trace elements within permissible limits per ASTM standards
This chemistry underscores the performance: manganese is the primary hardening chemic, with modest additions of copper enhancing strength while silicon and iron presence help control weldability and surface quality.
Mechanical Properties of 1mm 3003/3004 H111 Aluminium Sheets
| Property | Typical Value |
|---|---|
| Tensile Strength (MPa) | 130 – 215 |
| Yield Strength (MPa) | 100 – 180 |
| Elongation (%) | 4 – 10 |
| Hardness (Brinell) | 40 – 60 |
(Note: Values depend on tempering exactitude and rolling process)
This reveals that though 1mm thickness indicates a thin gauge alloy sheet, its strain-hardening H111 condition brings sufficient strength and stiffness for diverse applications—including but not limited to:
- Building facade cladding
- Trailer paneling
- Lettering and signage substrates
- Furniture and appliance components
- Superior Forming/Workability: Compared to fully annealed states, H111 achieves elevated strength without sacrificing ductility; reducing production defects related to cracking or spring-back.
- Corrosion Resistance: Darwin’s wet and dry environments profoundly affect metals; 3003/3004 fields excellent resistance owing to manganese enrichment.
- Weldability: Ensures solid joints suitable for tig/mig and spot welding processes, critical to fabrication.
- Surface Finishing Compatibility: Well-suited for anodizing and painting due to low iron and silicon content.
Environmental and Practical Considerations
