Goodfellow offers a wide range of gold plated wire tungsten wire with 171 variations to choose from. This gold coated tungsten wire combines the high tensile strength and modulus of tungsten with the excellent conductivity and corrosion resistance of gold. These wires can be used for applications requiring high strength and flexibility including microelectronics, medical devices, aerospace systems, and radiation shielding. The gold plating protects the tungsten core from oxidation while allowing electrical signals to pass through the wire. Goodfellow's selection of gold plated wire tungsten wire covers a diverse range of sizes and specifications to meet your application requirements.
