Tantalum Mesh

Tantalum Mesh is made from high-purity tantalum metal, offering excellent corrosion resistance, high melting point, and good mechanical strength. It is widely used in chemical processing, medical, and electronic industries, such as for filtration materials, implantable medical devices, or structural components in high-temperature environments. Its unique chemical stability and biocompatibility make it ideal for demanding applications.

Tantalum Mesh Types And Applications

Shanghai Yuepeng offers high-precision tantalum mesh in expanded, stamped, and woven forms, each tailored to meet specific application needs. We provide customized solutions based on individual requirements. Below are the regular specifications for each mesh type:

• Woven Tantalum Mesh: Made by interlacing tantalum wire into a mesh, this type offers superior flexibility and high tensile strength. Woven mesh is commonly used for filtration, catalyst support, and as a protective barrier in a variety of industries, including the medical, nuclear, and electronics sectors.
• Expanded Tantalum Mesh: This mesh is made by expanding solid tantalum sheets into a uniform grid pattern, offering excellent flexibility, durability, and strength. It is commonly used in filtration, separation, and protective applications, especially in high-temperature and corrosive environments.
• Stamped Tantalum Mesh: Manufactured by stamping or punching a pattern from a solid tantalum sheet, this mesh is ideal for applications requiring precise, strong, and durable mesh with specific hole patterns. It is widely used in chemical processing, electronics, and aerospace industries where uniformity and precision are essential.
