Blue film cladding mirror aluminum strip coil 1100 H18
Blue film cladding mirror aluminum strip coil 1100 H18 is a high-purity aluminum strip engineered for applications that demand a high-reflectivity mirror finish with reliable surface protection during processing and transport. By combining the corrosion-friendly nature of AA1100 with the strength and stability of the H18 temper, this product delivers a clean, bright appearance and consistent performance in roll-forming, bending, stamping, laminating, and decorative fabrication.
The "mirror" surface is produced through controlled rolling and polishing processes to achieve a glossy, reflective face. The blue protective film is then applied to safeguard the finish from scratches, fingerprints, and minor abrasion-especially important for customer-facing parts or assemblies that must look pristine at installation.
What Makes 1100 H18 Mirror Strip Different
AA1100 is recognized for its very high aluminum content, which supports excellent corrosion resistance and an attractive, uniform surface. The H18 temper indicates a full-hard condition achieved by work hardening, offering improved strength and shape retention compared with softer tempers. When paired with a mirror-grade finish, 1100 H18 becomes a practical choice for decorative trims, reflectors, nameplates, and protective cladding components.
The blue film cladding is more than packaging-it functions as a temporary "skin" that helps maintain yield in downstream fabrication. It reduces rework from cosmetic defects and supports cleaner handling on automated lines.

Chemical Composition (AA1100)
AA1100 is a commercially pure aluminum alloy. Limits vary slightly by standard, but the following values are widely used for product selection and quality control.
| Element | Typical Limit / Range (wt. %) |
|---|---|
| Al | ≥ 99.00 |
| Si + Fe (combined) | ≤ 0.95 |
| Cu | ≤ 0.05 to 0.20 |
| Mn | ≤ 0.05 |
| Zn | ≤ 0.10 |
| Others (each) | ≤ 0.05 |
| Others (total) | ≤ 0.15 |
Note: Final certification values depend on melt, standard, and customer specification.

Typical Mechanical & Physical Data (Reference)
Values depend on gauge, processing route, and standard. The table below is useful for quick engineering comparisons.
| Property | Typical Value (1100 H18) |
|---|---|
| Tensile Strength | ~130–170 MPa |
| Yield Strength | ~110–150 MPa |
| Elongation | ~1–5% (depends strongly on thickness) |
| Density | ~2.71 g/cm³ |
| Thermal Conductivity | High (typical of pure aluminum) |
| Electrical Conductivity | High (relative to alloyed grades) |
For forming-intensive parts, consult bend radius guidance and validate with trials, especially at thinner gauges or tight radii.
Mirror Surface & Blue Film: Practical Advantages
A mirror aluminum strip is judged as much by its surface uniformity as by its alloy. In customer-facing components, small scuffs can downgrade the entire assembly. The blue film helps keep the mirror face intact through slitting, recoiling, stamping, and transportation.
| Topic | Why It Matters | What to Specify |
|---|---|---|
| Mirror reflectivity consistency | Avoids "cloudy" appearance across batches | Target gloss/reflectivity metrics, sample approval |
| Surface cleanliness | Prevents stains and handling marks | Film type, clean packing, interleaf if needed |
| Film adhesion | Too high leaves residue; too low peels during forming | Standard / low / high-tack options |
| Peeling behavior | Fast removal without tearing improves productivity | Peel angle expectations, aging conditions |
| Scratch resistance | Reduces cosmetic rejects | Handling requirements, protective film thickness |
Processing Notes for Fast, Reliable Fabrication
1100 H18 is strong and springy compared with annealed grades. It performs well in many high-speed operations, but it benefits from correct tooling and process control.
| Process | Recommended Practice | Result |
|---|---|---|
| Slitting | Sharp knives, controlled tension, clean rewind | Smooth edges and fewer coil set issues |
| Bending / Roll forming | Use adequate inside radius, control springback | Cleaner geometry and less surface stress |
| Stamping | Proper lubrication, polished dies, manage burr | Stable production with reduced marking |
| Lamination / Bonding | Confirm film removal timing and surface prep | Better adhesion and fewer trapped defects |
| Storage | Keep dry, avoid heat aging of film | Clean peel-off and stable appearance |
Where Customers Use Blue Film Mirror 1100 H18 Strip
This product is chosen when appearance and protection are as important as the base metal.
Lighting and Reflective Components
Mirror-finish aluminum helps improve light utilization in fixtures, trims, and reflectors. The blue film protects the optical surface while parts move through bending, spot assembly, and packaging.
Common uses include lamp reflectors, decorative light trims, LED channel accents, and bright internal panels.
Decorative Trims and Architectural Details
For interiors, appliances, and commercial displays, mirror aluminum offers a modern look without the weight or brittleness of glass mirrors. AA1100's corrosion-friendly nature supports long-term visual stability in many indoor environments.
Common uses include ceiling trims, wall edging, retail display bands, signage borders, and elevator or panel accents (where design permits).
Appliance and Consumer Product Accents
Mirror strip provides crisp highlight lines and premium visual cues. The full-hard temper helps maintain shape on thin, narrow profiles that must stay straight.
Common uses include appliance trims, nameplate backers, decorative rings, protective edging, and bright cover components.
Cladding and Protective Skins
In selected designs, mirror aluminum can serve as a bright cladding layer over substrates. The blue film reduces handling defects during installation, especially on long, narrow strips.
Common uses include protective facings, decorative cladding strips, and bright enclosure bands.
