Woven Aluminium Mesh | Aluweave Conductive Gaskets

General Information

Aluweave is a versatile, highly conductive gasket medium produced by filing a woven aluminium mesh with either silicone, fluorosilicone or neoprene rubber. It is particularly useful where thicker emi shielded gaskets are unsuitable but, because it is woven, it is not viable for 'landwidths' of less than 3mm for diecut gaskets. Surface irregularities should not exceed 0.05mm. This material is generally supplied as pre-cut gaskets constructed to the customers specific requirements but can also be supplied in sheets. Our range of EMI Shielded connector gaskets include Aluweave materials.

Applications

Aluweave filled aluminium mesh is used for emi connector gaskets and other 'thin' EMI gasket applications. If aluminium is unsuitable because of galvanic compatibility or shielding effectiveness, the expanded Monel based Monex may be more appropriate.

Aluweave gaskets provide good 'point contact' where each crossover occurs, while the rubber filler ensures excellent environmental sealing. Aluweave, like nearly all other conductive gasket materials, should not be fixed with a conductive or pressure sensitive adhesive and should be fixed as a friction fit utilising the fixing screws to position the gasket before tightening.
