1100 Embossed Aluminium Plates are among the most popular choices in the aluminum family, particularly prized for their excellent corrosion resistance, superior formability, and inherent anodizing qualities. The embossing process specifically adds a textured surface finish that combines aesthetic appeal with increased slip-resistance and mechanical stiffness without sacrificing the material’s intrinsic qualities.
Primarily utilized in architectural cladding, automotive interiors, elevator panels, decorative installations, and other industrial applications, 1100 embossed plates deliver brilliance and functional durability for both industrial and commercial environments.
Alloy Composition and Chemical Properties
The 1100 aluminum grade is defined by its high purity with a minimum of 99.0% aluminium content according to the Aluminium Association. Its simplified alloying system results in the following chemical composition, essential for its behavior during embossing, forming, and finishing.
| Element | Percentage (%) |
|---|---|
| Aluminium (Al) | 99.0 min |
| Copper (Cu) | ≤ 0.05 |
| Iron (Fe) | ≤ 0.95 |
| Manganese (Mn) | ≤ 0.05 |
| Silicon (Si) | ≤ 0.95 |
| Zinc (Zn) | ≤ 0.10 |
| Titanium (Ti) | ≤ 0.03 |
| Others | ≤ 0.05 |
This chemical purity accounts for excellent corrosion resistance making the alloy stable in harsh environmental conditions.
Temper Designations and Mechanical Properties
1100 aluminium plates are commonly available in O (annealed) and H14 (strain hardened and partially annealed) tempers, with cooling and stamping processes differing between them, impacting hardness and ductility.
| Temper | Description | Ultimate Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|---|
| O | Annealed (soft, highly formable) | 90-110 | 30-50 | 20-35 |
| H14 | Hardened by strain and partially annealed | 120-145 | 110-135 | 4-10 |
For embossed applications, H14 temper often is preferred to maintain a distinct emboss pattern stiffness without skewing the formability excessively.
Physical and Mechanical Specification Standards
implementation standards often adhered to include:
- ASTM B209: Standard specification for aluminum and aluminum-alloy sheet and plate defining basic thickness and quality requirements.
- AA (Aluminium Association) Standards: Especially for classification and alloy identification.
- EN 485-2 (European Standard): For aluminum sheets ensuring mechanical properties and tolerances.
Properties aligned with standards:
- Density: 2.71 g/cm³
- Thermal conductivity: ~222 W/m-K
- Electrical conductivity: ~63 % IACS
- Melting Range: 652-657°C
Embossing Characteristics and Advantages
The embossing process involves cold working the 1100 plate surface to create raised or recessed decorative patterns with various designs such as diamond, stucco, spangle or woodgrain finishes. Controlled rolling pressure ensures the product maintains structural integrity post-process.
Advantages include:
- Improved rigidity due to increased moment of inertia via emboss texture
- Slip resistance on flooring or shared high-traffic surfaces
- Enhanced aesthetics for architectural/decorator usage
- Easier handling & cleaning due to textured surface
- Electron beam or chemical anodizing is improved on these embossed surfaces
Typical Applications of 1100 Embossed Aluminium Plates
Located at the crossroads of industrial and decorative usage, 1100 embossed plates find prolific use in:
- Architectural malling & cladding systems
- Elevator facings, escalators, and panels
- Chemical and food processing equipment
- Walkway and stair tread supports for non-drop safety
- Signboards & display systems needing scratch/abrasion resistance
- Furniture (cabinetry and street furniture)
Availability and Dimensions
- Thickness range: 0.3 mm up to 3 mm
- Sheet Widths: Up to 1500 mm (custom trimming also available)
- Customized embossing patterns: Based on project requirements.
Storage & Handling Recommendations
To avoid surface damage or oxidation between application:
- Store 1100 embossed sheets in dry, clean, ventilated areas
- Avoid stacking with heavy loads as softness of 1100 may cause warping or dents
- Internal wrapping with protective polymers or foam rolls for overseas shipment preferred
