Aluminum Alloy 8079 Aluminum Foil Tape Substrate (0.01–0.02 mm | 600–900 mm Width | Single-Sided Bright Finish)

Introduction

The 8079-O ultra-high-purity aluminum foil tape substrate (0.010–0.020 mm thickness, 600–900 mm width, single-sided super-bright annealed finish > 92 % reflectivity) is the world’s No.1 backing material for premium HVAC, electronics, aerospace and construction aluminium foil tapes.

• Alloy 8079-O: elongation > 12 %, pinhole ≤ 30 pcs/m², perfect dead-fold & tear resistance.

• Single-sided bright + passivation: zero oxidation, 100 % adhesive wettability, residue-free removal after 30 years.

• FDA 21 CFR 175.105 (indirect food contact), UL 723, RoHS/REACH compliant.
  Result: tapes that stay mirror-bright for 30 years, bond instantly at –40 °C to +200 °C, and run at 1000 m/min on high-speed coating lines.
