What Are 1060 H14 Mirror Aluminum Coils?
1060 H14 mirror aluminum coils are rolled products made from 1060 alloy, which has a minimum aluminum content of 99.6%. The H14 temper is a half-hard, strain-hardened condition that balances strength with formability, while the mirror finish is produced by multi-stage mechanical polishing to achieve a bright, reflective surface. Because the brightness comes from polishing rather than from a coating, the finish does not peel or fade over time.
Typical products comply with ASTM B209, EN 485-2 and GB/T 3880. The coils are widely used in architectural decoration, consumer electronics, furniture, sanitary ware, automotive trim and exhibition displays, where appearance and durability are equally important.
Core Properties
Reflectivity and surface quality: the polished surface typically achieves reflectivity of 90% or higher, with surface roughness Ra maintained at 0.02 μm or below. The mirror effect creates a clean, spacious visual impression and is stable under normal indoor and outdoor conditions.
Corrosion resistance: the high-purity base alloy forms a dense natural oxide layer that protects the material against atmospheric corrosion, fresh water and mild chemical exposure. This makes the coil suitable for humid environments with minimal maintenance.
Strength and formability: in the H14 temper, tensile strength is typically in the range of 100 to 140 MPa with elongation of about 10% or more, allowing bending, stamping and rolling into decorative shapes. A minimum bend radius of about twice the material thickness is a practical guideline for most sections.
Weight and recyclability: with a density of approximately 2.71 g/cm3, the coil is lightweight and easy to transport and install. Like all aluminum, it is fully recyclable, which supports sustainability objectives.
Technical Specifications
Alloy composition: aluminum 99.6% minimum; silicon up to 0.25%; iron up to 0.35%; copper up to 0.05%; manganese up to 0.03%; zinc up to 0.05%; other elements each up to 0.03%, in line with EN 573-3.
Mechanical properties (H14): tensile strength typically 100 to 140 MPa; yield strength typically 75 to 115 MPa; elongation 10% or more. Thermal conductivity is approximately 235 W/(m·K) and electrical conductivity about 60% IACS.
Dimensions: thickness commonly ranges from 0.15 mm to 3.0 mm; width from 800 mm to 2500 mm; coil weight from 300 kg to 3000 kg; inner diameter 508 mm or 610 mm. Thickness tolerance is typically 0.02 mm for gauges up to 1.0 mm and 0.05 mm for heavier gauges.
Surface options: beyond the standard mirror finish, the coil can be supplied with anodized, painted or printed surfaces for colored mirror and patterned effects.
Applications
Architecture and interior design: ceiling panels, column cladding, elevator cabins, wall panels, decorative screens and exterior facade trims benefit from the bright finish and natural corrosion resistance.
Consumer electronics and appliances: laptop and audio equipment shells, TV back panels and appliance decorative parts use the lightweight and premium appearance of the coil.
Furniture and sanitary ware: tabletops, cabinet doors, bathroom mirrors and shower enclosures take advantage of the easy-to-clean, water-resistant surface.
Automotive styling: interior trims, door sills and exterior decorative strips add a bright accent while contributing to weight reduction.
Exhibition and retail: display shelves, showcase frames and booth panels rely on the reflective surface to enhance product presentation.
Fabrication and Handling Points
Protect the polished surface during handling by keeping the protective film in place until the final step. Use soft slings and clean work surfaces to avoid scratches. When bending, respect the minimum bend radius for the H14 temper and use wiping dies or press brakes with polymer liners to preserve the finish. For slitting, use sharp, burr-free tooling. If the surface is to be anodized or coated, verify that the polishing lubricant is fully removed beforehand. Store coils vertically on dedicated racks in a dry warehouse to maintain flatness and surface condition.
FAQ
Q1: What does H14 mean in 1060 H14 mirror aluminum coil?
H14 is a strain-hardened temper equivalent to half-hard. It is cold worked to a level midway between annealed and fully hard, giving a practical combination of strength and formability.
Q2: Is the mirror finish a coating?
No. The mirror finish is produced by mechanical polishing of the aluminum surface, so it cannot peel or fade. Optional anodizing or painting can be applied for color effects.
Q3: What thickness is commonly used for architectural applications?
Gauges from 0.5 mm to 2.0 mm are typical for wall cladding, ceiling panels and decorative trims, while lighter gauges suit electronics and consumer goods.
Q4: Can the coil be anodized after polishing?
Yes. Anodizing can be applied to the polished surface to add color and improve wear and corrosion resistance, provided the surface is properly cleaned beforehand.
Q5: How should mirror coils be stored to avoid damage?
Keep the protective film intact, store in a dry indoor environment, and handle with soft slings so that the polished surface is not scratched or contaminated.
Q6: What standards cover 1060 mirror aluminum coil?
Common references are ASTM B209 for sheet and coil, EN 485-2 for dimensional tolerances, and GB/T 3880 for Chinese-market supply.
