Aluminum Alloy 3003 Aluminum Strip for Car Radiator Fins, Thickness 0.15–0.3mm, Customizable Width, Bright Annealed Condition

Product Deep-Dive: Why 3003 Beats Every Fin

1. Alloy DNA

   • 1.2 % Mn → 30 % stronger than 1050, 25 % cheaper than 8079

   • Zero burr after 500 m/min slitting

2. Bright Annealed Magic

   • H14 vacuum bright anneal, Ra < 0.08 μm

   • Zero oil, zero carbon → perfect brazing fillet

   • 300 W/m·K certified (laser flash)

3. Feather-Thin Muscle

   • 0.2 mm = 0.54 kg/㎡ → 1 radiator = 1.9 kg fins

   • 1 000 cars = 1.9 t less CO₂

4. Width Wizard

   • 12–1 200 mm slit in 0.05 mm steps

   • 100 mm standard feeds 98 % of fin machines

5. Surface Lab

   • Mirror-Bright standard

   • Hydrophilic, epoxy, flux-coated in 72 h
