Nickel mesh refers to a mesh or grid made from nickel or nickel alloys. This mesh can come in various forms, including woven wire mesh, expanded metal mesh, perforated metal mesh, or knitted wire mesh, depending on the manufacturing process used. Nickel mesh has a wide range of applications due to its unique properties. Here are some key characteristics and applications of nickel mesh:

Characteristics:

Corrosion Resistance: Nickel foam is highly resistant to corrosion, making nickel mesh suitable for use in chemically aggressive environments.

High Conductivity: Nickel has good electrical conductivity, which makes nickel mesh useful in electrical and electronic applications.

Heat Resistance: Nickel retains its properties at high temperatures, making it suitable for applications in high-temperature environments.

Ductility: Nickel is a ductile metal, meaning it can be easily formed and shaped into various configurations.

Applications:

Battery Electrodes: Nickel mesh is used in the manufacture of battery electrodes, particularly in rechargeable battery technologies like nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) batteries.

Electroplating: It is used as a substrate for electroplating processes to enhance the corrosion resistance and appearance of metal parts.

Chemical Filtration: Nickel strip is used in filtration applications, including chemical filtration and separation processes.

Catalyst Support: In chemical reactions, nickel mesh can serve as a support structure for catalyst materials.

EMI Shielding: It is employed in electromagnetic interference (EMI) shielding applications to block or reduce electromagnetic radiation in electronic devices.

Gas Diffusion Layers: In fuel cell technology, nickel mesh is used as gas diffusion layers (GDLs) to facilitate the movement of reactant gases in the fuel cell.

Aerospace: Nickel mesh finds applications in the aerospace industry, particularly in engine components and heat shields due to its heat resistance.

Chemical Processing: It is used in chemical processing equipment and reactors where resistance to corrosion and high temperatures is essential.

Decorative Applications: Nickel mesh can be used decoratively in architectural and interior design, as well as in jewelry and fashion accessories.

Overall, nickel mesh is a versatile material with excellent corrosion resistance, electrical conductivity, and thermal stability, making it valuable in a wide range of industries and applications.
