14µm Gold Coated Tungsten Wire

Our 14µm Gold Coated Tungsten Wire is a high-precision functional material that combines the inherent advantages of pure tungsten with the enhanced performance of a gold coating. Made of high-purity tungsten core and a uniformly plated gold layer, this ultra-fine wire with a diameter of 14 micrometers is engineered to meet the strict requirements of high-end, mission-critical applications. Tungsten's exceptional high melting point, high tensile strength and low thermal expansion coefficient are perfectly complemented by gold's excellent electrical conductivity, corrosion resistance and oxidation protection, making it a reliable choice for industries that demand precision, stability and long-term performance under harsh conditions. Whether for satellite communication, electronic devices, medical instruments or scientific research, this wire delivers consistent quality and outstanding performance that exceeds industry standards.

• The gold coating is tightly controlled, uniform and dense, with strong adhesion to the tungsten core, avoiding peeling or cracking even during complex processing. The shiny gold surface is not only aesthetically superior to ordinary black or white tungsten wire but also provides reliable protection for the core.
• Exceptional Mechanical & Thermal Performance: The high-purity tungsten core boasts an ultra-high melting point (3410℃) and excellent tensile strength, maintaining dimensional stability and no sagging even under high-temperature and high-vibration conditions. Its low thermal expansion coefficient ensures minimal deformation in extreme temperature changes, making it suitable for high-temperature instruments and harsh environment applications.
• Enhanced Corrosion & Oxidation Resistance: The gold coating effectively isolates the tungsten core from air, moisture and corrosive substances, significantly improving the wire's corrosion resistance compared to uncoated tungsten wire. This protection ensures long-term performance and service life in aggressive environments, including medical and industrial settings where corrosion resistance is critical.
• Excellent Electrical Conductivity: Gold's low electrical resistance enhances the wire's conductivity, ensuring stable signal transmission and reliable electrical connections. This makes it ideal for electronic components, wire bonding and high-frequency signal pathways where electrical integrity is essential. Additionally, the similar density of tungsten (19.25 g/cm³) and gold (19.3 g/cm³) means the wire's density remains almost unchanged, avoiding performance impacts due to weight changes.
• Versatile & Customizable: The 14µm diameter is suitable for a wide range of micro-applications, and we offer customizable gold coating thickness to meet specific application needs. The wire also features good winding performance, making it easy to process into complex shapes such as coils or meshes.

Our 14µm Gold Coated Tungsten Wire is widely used in high-end industries that require precision, stability and corrosion resistance, thanks to its unique combination of tungsten and gold properties. Key application areas include:

• Electronics & Semiconductors: Ideal for wire bonding in microchips, semiconductors, high-frequency devices and superconductors. It is also used in batteries, supercapacitors, photovoltaic (PV) cells and quantum computing components, where its fine diameter, high conductivity and thermal stability ensure reliable performance.
• Satellite Antenna: Applied in lightweight mesh antennas, high-frequency signal pathways, connectors and thermal sensors for satellites equipment. It withstands the harsh conditions of space environments, ensuring mechanical durability and electrical reliability.
• Medical Devices: Suitable for minimally invasive surgical tools, guide wires, spring coils, neurostimulation electrodes and surgical robotics. The wire's high density makes it highly visible under X-ray, guiding medical staff during procedures, while its corrosion resistance and biocompatibility meet strict medical safety standards (note: not for long-term in-vivo implantation).
• Industrial & Printing: Used as electrode wires (corona wires) in copiers, replacing corrosive pure tungsten wire. It is also applied in air ionizers, negative ion generators, high-temperature instruments and microscopes, where corrosion resistance and stability are essential.
