Micro Expanded Metal Mesh (DIN 791) is used for battery current collectors, lightning-strike protection, EMI shielding and fine supports made from thin foil expanded into a micro diamond mesh.
Also known as: micro expanded metal mesh, expanded metal foil, micro mesh, expanded aluminium mesh
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.
Micro Expanded Metal Mesh is stocked and supplied to order in rolls, cut sheets and fabricated pieces. Pricing starts from approximately US$20.00 per unit for standard specifications in stainless steel 304; final pricing depends on specification, alloy, quantity and fabrication (MOQ applies).
