Nickel Iron Mesh For Sealing Glass-to-Metal And Shielding Against EMI In Industrial And Electronic Applications
Nickel-iron mesh is a durable and versatile material composed of woven or welded wires made from an alloy of nickel and iron. Known for its high strength, excellent corrosion resistance, and magnetic properties, it is widely used in industrial, electrical, and aerospace applications. This mesh is particularly effective in electromagnetic interference (EMI) shielding, making it valuable in electronic enclosures and sensitive equipment. Its heat resistance and chemical stability also make it suitable for high-temperature environments and chemical processing. Nickel-iron mesh is available in various mesh sizes and weaves, offering flexibility for different needs. Overall, this mesh is favored for its combination of mechanical strength, magnetic shielding, and corrosion resistance in demanding applications.
