Special Materials

Special Materials refer to high-performance metallic materials specifically designed for advanced engineering and high-precision applications. These materials usually combine excellent mechanical strength, electrical conductivity, corrosion resistance, and lightweight characteristics, making them widely used in, satellite communication, microwave engineering, and electromagnetic protection fields.

At SATA, Special Materials mainly include ultra-thin coated metal wires and high-precision metal meshes. Through advanced physical coating technologies, we can deposit a metal layer such as gold, silver, copper, nickel, or titanium onto a core metal wire made of tungsten or molybdenum. This technology significantly improves the electrical conductivity, reliability, and environmental resistance of the materials while maintaining extremely small diameters and lightweight structures.

Among our product portfolio, Gold Coated Molybdenum Wire and Gold Coated Molybdenum Wire Metal Mesh are widely used in satellite deployable antennas, shielding fabrics, microwave protection structures, and high-frequency electronic devices. With our own production lines and advanced weaving technologies, SATA is able to provide customized material solutions that meet strict technical requirements for high-end precision industries.

SATA's Special Materials are developed to meet the demanding performance requirements of high-end precision and high-frequency communication systems. These materials offer a unique combination of reliability, precision, and customization capability.

1. Ultra-Thin Precision Manufacturing

Our metal wires can reach extremely small diameters such as 17 μm, 20 μm, 25 μm, and 27 μm, enabling lightweight structures while maintaining high strength and stability. Custom diameters ranging from 14 μm to 200 μm are available upon request.

2. Advanced Physical Coating Technology

Compared with traditional electroless plating methods, our physical coating technology produces a more uniform and reliable metal layer, significantly improving durability and electrical performance.

3. Excellent Electrical Conductivity

Gold and silver coatings provide superior conductivity and low signal loss, making these materials ideal for high-frequency microwave and satellite communication applications.

4. High Strength and Lightweight Structure

The molybdenum and tungsten core wires provide excellent mechanical strength while maintaining a lightweight design, which is particularly important for deployable structures and other high-precision requirements.

5. Corrosion and Temperature Resistance

Special materials can operate reliably in extreme environments with a standard temperature range of -196℃ to 250℃, and a maximum operating temperature of up to 450℃, ensuring stable performance under demanding thermal conditions.

6. Multi-Band Compatibility and High Reflectivity

Our metal mesh related products are optimized for different satellite communication frequency bands, delivering stable RF reflectivity across L/S, C, X, Ku, and Ka bands. Gold coated molybdenum wire mesh achieves reflectivity of ≥96%, while stainless steel mesh maintains ≥94% in C/Ku band applications, ensuring reliable signal transmission efficiency.

7. Flexible Customization Capability

Wire diameter, coating thickness, coating metal type, mesh aperture size, density, tension properties, and electrical performance can all be customized to meet specific engineering requirements.

Types of Special Materials

 

SATA offers several types of special materials designed for different deployable antennas and electromagnetic applications.

Gold Coated Molybdenum Wire

Gold coated molybdenum wire is produced by depositing a thin gold layer onto a molybdenum core wire using advanced physical coating processes. This structure combines the mechanical strength of molybdenum with the excellent conductivity and corrosion resistance of gold. We offer ultra-thin diameters as standard stock items, including 17 μm and 27 μm, and we also support custom diameters ranging from 14 μm to 200 μm upon request. Lightweight, durable, and highly conductive, these wires are well suited for high-frequency electronic applications, electric vacuum devices, and high-end precision engineering projects.

Gold Coated Tungsten Wire

Gold coated tungsten wire is manufactured with high-purity tungsten as the core material and a gold surface layer applied through advanced physical coating processes. Tungsten offers higher tensile strength than molybdenum, which makes this product especially suitable for applications that demand both excellent conductivity and superior mechanical robustness. We stock standard diameters of 14 μm, and we can also accommodate custom diameters from 14 μm to 200 μm as required. These wires are widely used in high-reliability electronic components, electric vacuum devices, and precision instruments.

stainless steel wire and related metal mesh

We offer stainless steel (316L) precision wires and metal meshes as a cost-effective alternative for applications that do not require gold coating. These products are available in wire diameters ranging from 10 μm to 50 μm, with 30 μm and 50 μm held as standard stock items. Stainless steel wire mesh delivers stable RF reflectivity across L/S, C, X, and Ku bands, achieving reflectivity of ≥94% in C/Ku band applications. These materials are well suited for electromagnetic shielding, industrial filtering, microwave protection systems, and other general-purpose high-frequency uses where cost-effectiveness is a primary consideration.

Gold Coated Molybdenum/Tungsten Wire Metal Mesh

Gold coated wire metal mesh is manufactured using ultra-thin metal wires (10 μm–30 μm) and advanced weaving techniques. The mesh structure can be customized with different hole sizes, density levels, and tension properties to meet specific application requirements. Our metal mesh products offer high microwave reflectivity (≥96%), uniform structure, isotropic mechanical and electrical properties, and excellent temperature resistance (-196℃ to 250℃). We provide mesh products optimized for different frequency bands, including L/S Band, X Band, and Ku/Ka Band variants. In addition to molybdenum-based mesh, SATA can also manufacture gold coated tungsten wire mesh and stainless steel mesh according to customer requirements.

We provide fully customizable material solutions to meet diverse engineering requirements. The following parameters can be tailored according to your project specifications:

• Wire diameter（available from 14 μm to 200 μm; stock diameters: 17μm, 27 μm）
