Aluminum Alloy 3105 Coils for Air Conditioner Heat Exchangers (0.3–0.5mm, Anti-Corrosion Coating, Custom Width)

Introduction

The 3105 aluminum alloy coils (0.3–0.5mm thickness, customizable width, dual anti-corrosion coating) are engineered for next-generation air conditioner heat exchangers. With 0.3-0.8% Mg and 0.2-0.8% Mn, 3105 delivers 10% higher strength than 3003 while retaining superb formability and thermal conductivity (~160 W/m·K). The proprietary hydrophilic + epoxy coating system achieves zero water bridging, 1000h+ salt-spray resistance, and 15% higher heat exchange efficiency. Custom widths (100-1650mm) and colors (blue/gold) enable seamless integration into high-density fin stamping lines, making it the material of choice for energy-efficient, long-life AC systems.
