There are many kinds of tungsten wires: black tungsten wire, white tungsten wire, tungsten rhenium wire, gold-plated tungsten rhenium wire, anti-sagging tungsten wire, and gold plated tungsten wire, etc. Here we mainly talk about gold-plated tungsten wire.

Gold-plated tungsten wire means tungsten wires coated with a layer of gold. Gold-plated tungsten rhenium wire is tungsten rhenium wire with gold-plated. Tungsten wire and tungsten rhenium wire with gold-plated have similar appearance, but different material content. And the properties of tungsten wire and tungsten rhenium wire are different. 

 

 

Gold-plated tungsten wire has a bright and gold shining surface. Tungsten wire has high temperature resistance, corrosion resistance, high melting point, low thermal expansion, which is suitable for using as tungsten filament, and tungsten heater. Gold-plated tungsten wire increases the corrosion resistance of tungsten wire.In appearance, gold-plated tungsten wire is much more beautiful and brighter than black tungsten wires, cleaned tungsten wires and sprayed tungsten wires. In a deeper sense, gold-plated tungsten wire has higher corrosion resistance than common tungsten wires. Tungsten has high melting point, high resistivity, good strength and low vapor, which is the best material for making incandescent filament in all pure metals. 

 

Gold-plated tungsten wire is used as the electrode wire of the copier which replaces the caustic tungsten wire and tungsten aluminum wire. It can also be used as an ideal corrosion resistant electron emission material, which is widely used in high energy physics, meteorology and other research fields. It can be used to make all kinds of antennas, or some projects have special requirements for high performance materials. Special fine, high precision tungsten plated tungsten wire can be used as anode wire of control system detector to ensure its safe and reliable movement. Gold-plated tungsten wire quality can be identified mainly from the surface morphology, adhesion, elliptic degree and thickness. You also can consider the tensile strength, sag resistance, straightness, wear resistance, plasticity, life.
