All mesh EMI/RFI knitted wire gasketing is available in various cross sections to satisfy the many different requirements encountered in shielding applications. The choice between rectangular, round, round with fin or double round with fin depends on the enclosure or equipment to be shielded.
Each strip has the same resiliency created by the knit construction but reacts differently dependent on material and shape. Of the most common materials used, Monel has the best spring factors while silver-plated brass has the highest conductivity. All mesh gasketing which is rectangular or round is recommended for grove mounting while single round with fin or double round with fin is recommended for flat surfaces. Surface conditions must be clean and free from such contamination as paint or oil for good conductivity and there should be an even distribution of pressure continuously along the length of the gasket.
A wide range of knit wire mesh materials are available. The standard knit wire mesh is either Monel or tin-plated ferrous. While these are standar, aluminum, silver-plated brass, gold-plated copper, tungsten, stailess stell, silver, nickel, iconel, and other wire can be knit and fabricated into special products.
