1050 1060 alloy 0.3 mm thick mirror aluminum coil
The 1050 and 1060 aluminum alloys are commercially pure aluminum grades (≥99.5% & ≥99.6% Al respectively) known for excellent corrosion resistance, high electrical and thermal conductivity, good ductility, and excellent formability. When produced as a 0.3 mm thick mirror-finish coil, these alloys provide a bright, highly reflective surface ideal for decorative and functional applications where reflectivity, corrosion resistance, and malleability are required.
highlights:
- Alloy grades: 1050 (Al ≥ 99.5%), 1060 (Al ≥ 99.6%)
- Thickness: 0.30 mm (± tolerances)
- Surface: Mirror polish (high gloss, bright reflective)
- Form: Coil (slit/trimmed to customer width)
- Common tempers: O (soft, annealed); H14/H16 (lightly work-hardened) depending on application

Surface Treatment & Mirror Finish
The mirror coil receives precision polishing and protective treatments to maintain surface quality during handling and processing.
Common processes:
- Mechanical polishing using progressively finer abrasives to achieve high gloss.
- Chemical brightening (optional) for enhanced reflectivity and removal of micro-oxides.
- Protective PE film on one or both sides to prevent scratching during transport and forming.
- Anti-fingerprint coats available on request for decorative/consumer applications.
Typical reflective performance:
- Specular reflectance comparable to polished aluminum: 80–90% in visible spectrum (depends on exact polishing method and measurement wavelength).
Fabrication & Processing Recommendations
- Cutting: Shearing, laser cutting, and slitting are appropriate; use sharp tools to minimize burr and deformation.
- Forming: Excellent formability in O temper; for deep draws use annealed O temper to avoid cracking.
- Welding: Can be welded by TIG, MIG; pre-cleaning required to remove surface film/contamination.
- Anodizing: 1050 / 1060 can be anodized, but color acceptance is limited due to high purity; pre-anodizing polishing may be required.
- Adhesive bonding: Good surface for adhesives after proper cleaning/priming.
- Bending radius: Maintain larger inside radii for thinner gauges; test with specific tooling to avoid cracks.
Typical Applications
The mirror-finish 0.3 mm 1050/1060 aluminum coil is used where high reflectivity, corrosion resistance, and light weight are needed:
- Decorative interior and exterior architectural elements (ceiling panels, trims, signage)
- Reflectors and light housings (LED reflectors, lamps, luminaries)
- Consumer goods and appliances (decorative panels, nameplates, housings)
- HVAC and ducting where reflective surfaces are desirable
- Food and pharmaceutical packaging components (non-toxic, corrosion-resistant)
- Instrument panels and decorative automotive trim (non-structural)
- Mirrors for lighting and solar concentrators (where high specular reflectance required)
- Craft and signage industries (stamped/formed decorative parts)
Quality Control & Inspection
Standard quality control performed on each coil:
- Visual inspection for surface defects (scratches, pits, roll marks)
- Dimensional inspection (thickness, width, flatness)
- Mechanical test (tensile, elongation) per batch
- Chemical analysis (spectrographic) with MTR provided
- Surface reflectivity measurement on request
- Packaging inspection to ensure protective film and packing integrity
Acceptable defect criteria and tolerance classes are defined per agreement and applicable standards (ASTM/EN/JIS).
Packaging & Delivery
Typical packaging options:
