Aluminum Strip vs. Aluminum Foil: Key Differences and Applications

While aluminum strip and aluminum foil are both made from high-purity aluminum, they serve very different industrial and commercial purposes. Choosing the right material depends on your project's mechanical, thermal, and electrical requirements.

Key Differences

Property Aluminum Strip Aluminum Foil
Thickness 0.2 mm – 6.0 mm < 0.2 mm (often 0.006 – 0.15 mm)
Mechanical Strength High, suitable for structural and winding use Low, flexible and delicate
Applications Transformers, reactors, electrical panels, fins Food packaging, insulation, EMI shielding
Processing Slit from coil, edge treated Rolled to thin gauge, often laminated
Conductivity Excellent (used for power distribution) Good (used in shielding and flexible circuits)

When to Use Aluminum Strip

  • Electrical winding: Preferred for transformer and reactor coils
  • Heat exchangers: Offers robust heat transfer and structural integrity
  • Panel reinforcement: Structural aluminum parts with conductivity

When to Use Aluminum Foil

  • EMI/RFI shielding: In electronics and cable wrapping
  • Thermal insulation: HVAC, building wrap, duct tape
  • Food and pharmaceutical packaging: Hygienic and barrier-safe

Summary Table of Use Cases

Application Preferred Material
Transformer winding Aluminum Strip
Cable shielding Aluminum Foil
Flexible packaging Aluminum Foil
Heat sinks and fins Aluminum Strip
Flexible printed circuits Aluminum Foil

Choose aluminum strip when mechanical strength, electrical conductivity, and durability are key. Choose aluminum foil when flexibility, insulation, or packaging is your priority.
