Products: Aluweave - Versatile Gaskets | GA Series

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 gaskets are unsuitable but, because it is woven, it is unsuitable for 'landwidths' of less than 3mm for diecut gaskets. Surface irregularities should not exceed 0.05mm. This material is available in two thicknesses – 0.4mm and 0.5mm ± 0.1mm – and is generally supplied as pre-cut gaskets constructed to the customers specific requirements but can also be supplied in sheets. Connector gaskets in the DC Series include Aluweave materials.

Applications

Aluweave is used for connector gaskets and other 'thin' gasket applications. If aluminium is unsuitable because of galvanic compatibility or shielding effectiveness, the expanded Monel based GX Series 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.
