Gold-plated Tungsten Wire
Gold-plated Tungsten Wire Description
Gold is the most commonly used thin coating material and does not chemically react under normal conditions. Gold and tungsten have exactly the same density, but their mechanical properties and melting temperatures vary.The most common way to combine the two is to plate gold on the tungsten wire to form a very thin gold-plated layer, which can improve the wettability during welding, prevent chemical corrosion, reduce the secondary emission of electrons, and achieve good performance. electrical contact and conductivity. Gold-plated tungsten wires have the advantages of good tensile strength, strong wear resistance, good plasticity, strong durability, superior oxidation resistance and low production cost.
Gold-plated Tungsten Wire Application
Gold-plated tungsten wire is widely used in medical, printing, chemical, optoelectronic physics and meteorology. Gold-plated tungsten wires are also often used as corona wires for copiers, lead wires for air purifiers and dust collectors, corrosive electron-emitting materials, braided satellite antennas, and wires in radioactive material detection instruments.
