Aluminum Alloy 8011 Aluminum Foil for Transformer Winding (0.03 mm | Custom Width | Bright Surface)

Introduction

The 8011-H18/O high-conductivity aluminum foil for transformer winding (0.030 mm thickness, 300–1500 mm customizable width, double-side ultra-bright annealed surface) is the global power industry’s first choice for distribution & power transformers, replacing copper foil in MV & HV windings.

• Purity ≥ 99.99 %, electrical conductivity ≥ 61.5 % IACS, burr height ≤ 0.01 mm.

• Bright annealed + edge-rounding treatment: zero micro-cracks, perfect layer-to-layer insulation.

• Meets IEC 60296, ASTM B736, GB/T 3190, RoHS/REACH standards.
  Result: transformers that reduce copper loss by 30 %, cut total weight 45 %, and allow 50 % faster continuous foil-winding speed than traditional copper.
