Embossed aluminum sheet 6082
Embossed aluminum sheet 6082 combines the mechanical strength of 6082 alloy with the functional and decorative advantages of an embossed (patterned) surface. It is widely used where anti-slip, durability, corrosion resistance, and an attractive appearance are required, such as in transportation, construction, flooring, and equipment cladding.
6082 is a heat-treatable Al-Mg-Si alloy with relatively high strength among the 6xxx series, good corrosion resistance, and decent weldability. When processed into an embossed sheet (such as diamond, orange peel, stucco, or other patterns), it offers enhanced aesthetics and slip resistance.

2. Chemical Composition of 6082
6082 is an Al-Mg-Si alloy with added manganese to improve strength and control grain structure.
Typical Chemical Composition (EN AW-6082)
| Element | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti | Others (each) | Al |
|---|---|---|---|---|---|---|---|---|---|---|
| wt.% | 0.7–1.3 | ≤0.50 | ≤0.10 | 0.4–1.0 | 0.6–1.2 | ≤0.25 | ≤0.20 | ≤0.10 | ≤0.05 | Balance |
Note: Exact composition may vary slightly according to standard, melt practice, and customer-specific requirements, but remains within the specified limits.
3. Mechanical Properties
Mechanical properties depend strongly on temper and thickness. The embossed process minimally impacts bulk mechanical properties but can slightly change surface hardness and rigidity.
Typical Mechanical Properties (Flat 6082 Sheet as Reference)
| Temper | Thickness (mm) | Tensile Strength Rm (MPa) | Yield Strength Rp0.2 (MPa) | Elongation A50 (%) |
|---|---|---|---|---|
| O | 1.0–6.0 | 130–180 | 60–110 | 14–22 |
| T4 | 1.0–6.0 | 205–245 | ≥110 | 14–20 |
| T5 | 1.0–6.0 | 240–290 | ≥180 | 8–12 |
| T6 | 1.0–6.0 | 260–310 | ≥240 | 8–12 |
Hardness (Brinell, HBW)
| Temper | HBW (typical) |
|---|---|
| O | 35–50 |
| T4 | 60–80 |
| T5 | 75–95 |
| T6 | 80–100 |
For embossed sheets, actual values are similar to base sheet but can vary slightly depending on final thickness after embossing and process conditions.

7. Processing & Fabrication Characteristics
7.1 Workability
| Operation | Performance & Recommendations |
|---|---|
| Bending | Good in O and T4; in T6 use larger bend radius to avoid cracking |
| Forming | Suitable for light to moderate forming; complex forming best in softer tempers (O/T4) |
| Cutting / Shearing | Good; use sharp tools for clean edges; consider pattern orientation |
| Punching | Feasible; allow for embossed geometry while designing punch dies |
| Machining | Good machinability, especially in T6; chips break easily |
| Welding (MIG/TIG) | Generally good weldability; strength in heat-affected zone reduced vs. base material |
7.2 Recommended Minimum Bend Radii (Guide)
(Values refer to bend radius for 90° bends across the rolling direction.)
| Temper | Thickness (mm) | Recommended Inner Radius (× t) |
|---|---|---|
| O | 1.0–3.0 | 0.8–1.0 |
| T4 | 1.0–3.0 | 1.0–1.5 |
| T6 | 1.0–3.0 | 2.0–3.0 |
For embossed sheets, select slightly larger radii than flat sheet due to the patterned surface.
8. Corrosion & Surface Treatment
