Nickel-Iron Mesh Versatile And Resilient Choice For Corrosive And High-Temperature Environments In Industry
Nickel-Iron mesh, also known as Ni-Fe or permalloy mesh, is a wire mesh made primarily from an alloy of nickel and iron. Known for its high magnetic permeability and excellent corrosion resistance, it’s widely used in electrical and magnetic applications, including shielding and transformers. This mesh can also be used in filtration, battery components, and aerospace applications where both strength and conductivity are crucial. Nickel-Iron mesh’s properties include good ductility, high strength, and stable performance under varying temperatures. Available in different weaves and thicknesses, it can be tailored to specific industrial needs. Overall, Nickel-Iron mesh combines durability, magnetic properties, and corrosion resistance, making it a versatile choice for both technical and engineering uses.
