The lighting industry celebrates the release of an all-new mirror finishing process for 1100 pure aluminum plates. Delivering 15% higher specular brightness and surface roughness below 0.05 μm, this breakthrough turns ordinary 1100 coils into super-reflectors that rival anodized classics, yet cost 30% less and weigh half as much. From stadium floodlights to satellite solar arrays, the new process redefines optical efficiency. This article covers properties, international applications, advantages, and 2025-2030 trends.
| Property | New Process | vs Traditional |
|---|---|---|
| Alloy | 1100-H18 | Same |
| Thickness | 0.3–2.0 mm | Same |
| Total Reflectance | 92–95 % | +15 % |
| Specular Brightness | 15 % ↑ (GU 1100+) | New record |
| Roughness Ra | ≤ 0.05 μm | 60 % smoother |
| Orange-peel | Zero (DOI ≥ 98) | Eliminated |
| Hardness | 45 HB (post-polish) | +10 % |
| Standards | ASTM B209, EN 485-2 | Fully compliant |
| Region | Project Example |
|---|---|
| North America | New York Hudson Yards 100 000 m² LED ceiling |
| Europe | Munich Olympic Stadium retrofit (90 000 lux) |
| Asia | Shenzhen Metro Line-14 full-aluminum reflectors |
| Middle East | NEOM “The Line” solar-concentrator street lamps |
Hot Uses
The new mirror finishing process for 1100 aluminum plates lights up the world, literally. With 15% brighter, zero-defect, and fully green reflectors rolling off lines in North America, Europe, and Asia, lighting engineers finally get more lumens for less money and zero guilt. From Hudson Yards to NEOM, the future is reflective, recyclable, and already shipping.
