5mm Thickness 1100 Alloy Aluminium Sheet Plate
When it comes to aluminum sheet plates, the 5mm thickness 1100 alloy variant holds a unique position that often gets overlooked in favor of more complex alloys. However, this material from an insider's lens reveals its unmatched balance of purity, workability, and corrosion resistance, making it an indispensable asset across industries.
What Makes 1100 Alloy Aluminium Sheet Plates Special?
1100 alloy aluminum is known as the "commercially pure" aluminum grade, containing at least 99% aluminum content. This high purity is not simply a number. It translates into excellent corrosion resistance and superior anodizing outcomes. The 5mm thickness, meanwhile, fares well between being sturdy enough for structural applications and flexible enough for precise machining and forming.
From an implementation standpoint, such sheets adhere to rigorous standards:
- ASTM B209 – Standard specification for aluminum and aluminum-alloy sheet and plate.
- AA (Aluminum Association) designation of 1100.
- Generally available in various tempers such as O (annealed), H14 (strain-hardened), giving specific mechanical properties adapted to the application's needs.
Tempering Conditions and Their Impact
how temper affects the 1100 alloy sheet plate’s behavior multiplies its forms of utility:
| Temper Code | Processing | Characteristics |
|---|---|---|
| O | Annealed | Maximum ductility, excellent formability |
| H14 | Strain Hardened (half hard) | Improved strength, moderate ductility |
| H18 | Strain Hardened (full hard) | Highest strength, reduced ductility |
Typically, the 5mm thickness 1100 alloy is supplied in the O temper because it allows easier fabricators’ handling and smoothing—excellent for applications requiring shaping or bending.
Chemical Composition – Pure and Simple
Let's d
| Element | Percentage (%) |
|---|---|
| Aluminum (Al) | 99.0 min |
| Copper (Cu) | 0.05 max |
| Iron (Fe) | 0.95 max |
| Manganese (Mn) | 0.05 max |
| Silicon (Si) | 0.95 max |
| Zinc (Zn) | 0.10 max |
| Others (each) | 0.05 max |
| Others (total) | 0.15 max |
This ultra-pure makeup allows not only for exceptional anti-corrosion performance, especially in marine or highly corrosive environments but also superb workability, lending to diverse applications from fly liners to decorative components.
Typical Applications and Use Cases
Often underrated, these 5mm 1100 alloy sheets shine when corrosion resistance rivals strength requirements. Popular uses include:
- Chemical processing equipment lined with aluminum resistance.
- Architectural paneling where lightweight and graceful anodized finishes matter.
- Electrical components thanks to its excellent thermal and electrical conductivity.
- Food processing and packaging films that require non-toxic and non-reactive surfaces.
Knowing the ins and outs of this material allows clearer visualization and decision-making. For instance, its typically modest tensile strength (~130 MPa in O temper) won't replace stronger structural alloys but suits where weight savings, formability, and longevity reign supreme.
