1000 Series AA1050 AA1070 Aluminum Alloy Coil Lamp Reflector

1000 Series AA1050 AA1070 Aluminum Alloy Coil Used Lamp Reflector

Aluminum alloy coils are widely used in manufacturing lamp reflectors (for LED lights, spotlights,

streetlights, etc.) due to their high reflectivity, lightweight properties, corrosion resistance, and

excellent formability.

Key Advantages 

♦ Superior Optical Performance

Exceptional reflectivity: Untreated pure aluminum (AA1050) achieves >85% light reflectance,

reaching 90-95% with polishing/coating

Precise light control: Excellent ductility enables complex parabolic designs for accurate beam

direction

♦ Outstanding Thermal Management

High thermal conductivity (237W/m·K) effectively dissipates LED heat.

Wide temperature tolerance (-50°C to 250°C) for high-power applications.

♦ Optimal Strength-to-Weight Ratio

Low density (2.7g/cm³) - 65% lighter than stainless steel.

Tensile strength up to 210-280MPa (AA5052) for structural integrity.

♦ Excellent Formability

Ultra-thin processing capability (minimum 0.05mm) for miniaturization

Supports multiple forming methods (stamping, spinning, bending) with >98% yield rate.

♦ Enhanced Environmental Resistance

Natural oxide layer provides 1000+ hours salt spray resistance (AA5052)

Anodized surface hardness reaches HV500 (5× wear resistance improvement)

Application Examples

LED downlight reflectors: AA1050 with mirror polishing for maximum brightness.

Streetlight reflectors: AA5052 with anodizing for weather resistance.

Automotive headlight reflectors: AA6061 spun + vacuum-coated for precision optics.

Our Company Advantages
