1060 1100 3003 3105 5052 Color coated brushed aluminum coil
Color coated brushed aluminum coil combines the premium visual texture of brushed aluminum with the long-term protection and color consistency of coil coating. Produced from widely used alloys such as 1060, 1100, 3003, 3105, and 5052, this material is engineered for architectural cladding, ceiling systems, appliance panels, signage, transportation trims, and decorative interior projects where a metallic grain + stable coating performance are both required.
Unlike plain painted aluminum, brushed-and-coated coil delivers a distinctive linear grain that reduces glare, elevates perceived quality, and helps mask minor handling marks. With controlled surface preparation, stable coating systems (PE/PVDF), and consistent temper selection, it offers an excellent balance of formability, corrosion resistance, and aesthetics.
Color coated brushed aluminum coil is manufactured through a controlled process flow:
- Alloy selection based on strength, formability, and corrosion conditions
- Brushing (hairline) or scotch-brite finishing to generate uniform grain texture
- Chemical pretreatment (chromate-free options available) to improve adhesion
- Coil coating with PE or PVDF topcoats and matched primers
- Curing and inspection for gloss, color, film thickness, adhesion, and flexibility
The result is a coil product that can be slit, cut-to-length, roll formed, stamped, or laminated with excellent visual repeatability.

Alloy Selection Guide (1060 vs 1100 vs 3003 vs 3105 vs 5052)
| Alloy | Alloy family | Core advantage | Best-fit scenarios |
|---|---|---|---|
| 1060 | 1xxx (Al ≥ 99.6%) | Very high ductility, excellent conductivity | Decorative parts, deep forming, cost-driven projects |
| 1100 | 1xxx (Al ≥ 99.0%) | Stable forming + widely accepted for coating | General decorative panels, appliance skins |
| 3003 | 3xxx (Al-Mn) | Good strength + good formability | Cladding, roofing, signage, general forming |
| 3105 | 3xxx (Al-Mn-Mg) | Better strength than 3003, commonly used in building sheets | Ceiling, corrugated profiles, building trims |
| 5052 | 5xxx (Al-Mg) | Strong corrosion resistance, higher strength | Coastal/industrial exposure, higher durability requirements |
Temper & Forming Notes
| Temper | Typical behavior | Common usage |
|---|---|---|
| O (Annealed) | Maximum ductility, lowest strength | Deep drawing, tight radius forming |
| H12 / H14 | Light strain hardening | General sheet forming, moderate stiffness |
| H24 | Strain hardened + partially annealed | Balanced forming + flatness, popular for coated products |
Grain direction matters for appearance. For panels, customers often specify brushing direction along the long side to ensure a consistent visual flow after installation.
Coating System Options (Appearance vs Durability)
| Coating type | Typical topcoat thickness | Weathering level | Typical use |
|---|---|---|---|
| PE (Polyester) | 15–25 μm | Good | Indoor, signage, general exterior with moderate exposure |
| PVDF (70% Kynar/Hylar class) | 20–30 μm | Excellent | High-end facade, strong UV, coastal zones |
Primer and pretreatment quality are critical. A robust pretreatment + primer improves adhesion, humidity resistance, and reduces the risk of edge creep in aggressive environments.
