Nickel Iron Mesh With Magnetic Properties Valuable In Electronic Enclosures And Sensitive Equipment

Nickel-Iron Mesh is a robust and versatile material crafted from a nickel-iron alloy, often referred to as permalloy or invar mesh. Known for its excellent magnetic shielding properties, it is widely used in electronic and electromagnetic applications, such as transformers, EMI shielding, and magnetic field containment. Nickel-iron mesh is also valued for its high mechanical strength, corrosion resistance, and thermal stability. It maintains consistent performance across a wide temperature range, making it suitable for aerospace, defense, and industrial uses. Available in various mesh sizes and weave patterns, it can be customized for specific applications. Overall, nickel-iron mesh offers a reliable solution for environments demanding precision magnetic control and durability.
