How to Specify Micro Expanded Metal Mesh

  • Foil thickness: 0.03–0.3 mm.
  • Pattern: Micro SWD × LWD and strand width set conductivity and weight.
  • Alloy: Copper, nickel, aluminum, stainless steel or titanium.

Materials

Standard supply is copper, stainless steel 304, stainless steel 316/316L; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.

Fitting & Care

  • Handle like foil to avoid kinks and creases.
  • Store copper and nickel mesh dry and sealed to prevent oxidation.

Common Mistakes

  • Choosing too narrow a strand for the current it must carry.
  • Using oxidized copper mesh for electrical contact.

When Micro Expanded Metal Mesh Is Not the Right Choice

Not a structural mesh — it is a thin functional layer.
