One common product you will find when dealing with EMI shielding is metal wire mesh. But what is metal wire mesh and what does it do? Metal wire mesh is a strand or wire knitted together creating a structure of woven and knitted shielding material.
Different types of metal wire mesh include non-hardenable types, hardenable types, nominal chemical composition nickel alloys, and austenitic types. Knitted metal wire mesh is very strong and durable with practical applications in air filtration, vibration dampening, EMI and RFI shielding, mist elimination, and even gaskets and sealing.
Welded stainless steel mesh is a certain kind of mesh that is used primarily in the fencing industry. Electro-galvanized is resistant to corrosion and is often used in the construction industry.
Metal Wire Mesh for EMI Shielding
Metal Wire Mesh used for EMI shielding is typically woven into a matrix pattern made of aluminum, monel, copper or bronze for the shielding of electromagnetic waves in vehicles, buildings, rooms and installations. It provides excellent shielding properties due to its metallic structure yet offers airflow for sensitive machines and devices.
MAJR Products makes several metal wire mesh products for EMI shielding needs. The engineering behind our metal wire mesh allows it to be made into multiple products for ambient electromagnetic noise attenuation, all while remaining light, flexible and durable. Between tapes, washers and gaskets there are literally 1000’s of possibilities for hundreds of applications.
MAJR Products’ EMI grounding washers are manufactured from knitted wire mesh stocking that is formed into a resilient metal washer by compressing in a close-tolerance forming die. The EMI grounding washer can be supplied in various diameters and thicknesses to satisfy the many requirements of civilian and military specifications.
MAJR Products’ Shielding Mesh Tape (1000 Series) is a knitted circular strip of knitted wire mesh providing an effective EMI shield often used for electrical and electronic cable assemblies. It can also be found in many of today’s industries in the assembly of RF-sensitive electronic equipment as an all-purpose EMI shield that is conformable and easy to integrate. The EMI knitted-mesh construction maximizes conform-ability and flexibility while minimizing bulk and weight.
Mesh Knitted Wire EMI Gasketing (1500 series) is available in various cross-sections to satisfy the many different requirements encountered in EMI shielding applications. MAJR’s knit wire gasketing material acts like thousands of tiny spring members, which are compressed and released with each opening and closing of a cabinet door or enclosure cover. The spring-like EMI mesh gaskets assure long life with consistent point-to-point contact, providing high shielding effectiveness and long life.
MAJR’s Mesh Over Elastomer EMI Gaskets offer the shielding effectiveness that can be expected from metal knitted mesh gaskets while simultaneously allowing for compression in a way that isn’t found with a typical all-mesh shielding gasket. A variety of material combinations are available to choose from depending on what sort of compression and shielding characteristics your specific application requires.
Because of its ability to be compressed, drawn through multiple dies or shaped into appropriate configurations – plus superior signal reflection or direction – MAJR’s metal wire mesh products are perfect for many places within civilian and military projects.
