More info

Gold-Coated Tungsten Wire is produced from ≥99.99% high-purity tungsten and coated with a uniform gold layer through advanced composite treatment to ensure structural stability and corrosion resistance. It offers a high melting point, excellent wire-winding properties, and strong machinability, making it ideal for various demanding applications. This wire is widely used in the production of lamp filaments, heating elements, vacuum coating heaters, and TIG electrodes. It also replaces traditional tungsten and tungsten-aluminum wires as corrosion-resistant electrode wires in copiers and similar devices. Additionally, gold-coated tungsten wire serves as an effective electron emission material in high-energy physics, meteorology, and research applications, as well as in the biomedical field. Heeger Materials provides high-quality Gold-Coated Tungsten Wire with consistent performance and reliability.

Gold-Coated Tungsten Wire Selection Notes

Gold-Coated Tungsten Wire belongs to the microelectronic interconnect wire range and is selected for controlled core and coating composition, fine-wire diameter, tensile behavior, elongation, surface cleanliness and spool consistency. It is commonly used in semiconductor packaging, LED and power-device interconnects, hybrid circuits, chip assembly and fine-wire bonding or welding process development. When requesting a quote, confirm core alloy, coating metal and thickness when applicable, wire diameter, tensile strength, elongation, electrical requirement, spool format, surface cleanliness, packaging, certification and quantity.
