Color Coating 1060 Aluminum Strips
Color Coating 1060 Aluminum Strips are made from commercially pure 1060 aluminum alloy, then finished with a controlled paint system to create a smooth, colorful, corrosion-resistant surface. With aluminum content above 99.60%, this material combines excellent ductility, high thermal conductivity, clean surface quality, and stable coating adhesion. It is widely used where lightweight metal, attractive appearance, and reliable processing performance are required.
Compared with ordinary bare aluminum strip, the color coating layer gives the strip better resistance to moisture, fingerprints, mild chemicals, ultraviolet exposure, and daily abrasion. For customers producing signs, channel letters, decorative edging, blinds, ceilings, closures, and electrical parts, it offers a practical balance of formability, appearance, and cost.
What Makes 1060 Aluminum Suitable for Color Coating
1060 aluminum is a non-heat-treatable pure aluminum alloy. Its low alloying content gives it a soft metallic structure, making it easy to slit, stamp, bend, roll form, and deep draw. The uniform substrate surface helps coating systems spread evenly, reducing orange peel, color variation, and pinhole risk.
The material is especially suitable for continuous coil coating. After cleaning and chemical pretreatment, primer and top paint are applied by roller coating and baked at controlled temperatures. The result is a finished strip that can be delivered directly to downstream production without extra painting.
For customers comparing coated products, Color Coated Aluminum Strip based on 1060 alloy is often selected when clean color, flexible forming, and economical production matter more than high structural strength.

Tempering Conditions and Mechanical Properties
1060 alloy cannot be strengthened by heat treatment. Its strength is controlled mainly by cold working and partial annealing. Softer tempers are selected for deep bending and shaping, while harder tempers are used for flatter panels and parts requiring better rigidity.
| Temper | Condition Description | Tensile Strength, MPa | Elongation, % Typical | Common Use |
|---|---|---|---|---|
| O | Annealed, soft | 60 to 95 | 20 to 35 | Deep drawing, tight bending |
| H12 | Quarter hard | 70 to 105 | 12 to 25 | Light forming and trimming |
| H14 | Half hard | 85 to 120 | 6 to 15 | Channel letters, signs, general parts |
| H16 | Three-quarter hard | 100 to 135 | 4 to 10 | Flat decorative components |
| H18 | Full hard | 120 to 160 | 2 to 6 | Slats, stiff narrow strips |
| H24 | Strain hardened and partly annealed | 85 to 120 | 8 to 18 | Balanced bending and flatness |
| H26 | Harder partly annealed | 100 to 135 | 5 to 12 | Roll-formed profiles |
Actual values depend on strip thickness, coil processing route, and agreed standard. For severe bending after coating, O, H12, H14, or H24 are usually preferred.
Coating Performance Data
The coating system is selected according to service environment. PE coating is economical and suitable for indoor or mild outdoor use. PVDF coating provides higher weather resistance, making it suitable for building exterior and long-term outdoor exposure.

Surface and Color Options
Customers can select solid colors such as white, black, red, blue, yellow, green, gray, and gold, as well as decorative patterns. Smooth glossy coatings are popular for signs and advertising materials, while matte finishes reduce glare for ceilings and interior panels. Metallic and embossed finishes add texture for premium trim and display applications.
Color control is normally managed by spectrophotometer. For repeat orders, color difference can be controlled by agreed Delta E tolerance, helping customers maintain consistent product appearance across batches.
| Surface Option | Visual Effect | Common Application |
|---|---|---|
| High gloss | Bright and reflective | Signs, decorative edging |
| Matte | Soft, low-glare finish | Ceilings, interior trim |
| Embossed | Textured surface | Blinds, wall decoration |
| Metallic | Premium metal appearance | Appliance trim, displays |
| Wood grain | Natural decorative look | Furniture and interior systems |
| Protective film | Scratch protection during fabrication | Stamping, bending, transport |
Processing Notes for Better Results
Before production, confirm bending radius, coating type, gloss, color tolerance, and end-use environment. For tight bending, the paint system should be tested with the selected temper and thickness. Slitting blades must be sharp to avoid burrs and coating flaking at the edge. During storage, coils should be kept dry, ventilated, and away from acidic or alkaline materials.
For outdoor applications, PVDF coating is recommended when strong sunlight, rain, salt air, or industrial atmosphere is expected. For indoor decoration and general fabrication, PE coating provides a cost-effective and attractive finish.
