The applications of the Pure Tungsten Wires: High vacuum electrode, Fluorescent filament, energy-saving lamp filament, HID electrode, Incandescent filament, fluorescent filament, energy-saving filament, printing needle, Halogen filament, high color temperature filament, automotive filament, Class C energy-saving high color temperature filament
Why does the quality of the bulb's Pure Tungsten Wire filaments not decrease after they are lit? Application of Pure Tungsten Wire-Heating Resistance Heating resistors are used in the production of electroplated picture tubes, mirrors, plastics, metals, and various decorative arts. The twisted tungsten wire is used as a raw material heating element, and it is also directly used as a heating accessory for semiconductor and vacuum equipment.
As the heating wire of the infrared heating tube, what is the difference between carbon fiber and Pure Tungsten Wire?
Features of Tungsten Wire-Heating Resistance After special treatment, the heating resistor is made of HW41 tungsten wire with a high melting point, corrosion resistance, and long life. Twisted tungsten wires are further made into tungsten heaters, which can be used for vacuum spraying and optical spraying.
Product features of Pure Tungsten Wire: The pure tungsten wire provided by PETROL STEEL uses high technology for adding, pickling, and static pressure processing, PLC-controlled direct sintering, extrusion forging, and automatic conveying.
These pure tungsten wire products have the following advantages: Minimal deformation in high temperature, high recrystallization temperature, and good castability. 5 kilograms of raw materials, welded into 3 kilograms of tungsten rod, this technology is currently leading in China.

Tungsten rhenium wire is an alloy wire composed of tungsten and rhenium. Advantages of tungsten rhenium wire: High strength at room temperature and high temperature, good plasticity after recrystallization, high resistivity, low resistivity, good oxidation and carbonization resistance, strong resistance to "water cycle reaction", and good welding performance.
Tungsten rhenium wire use: Color picture tube hot wire, various electron tube filaments, and grids. Tungsten rhenium wire is mainly used as a thermocouple material. Its advantages: fast response speed, wide temperature measurement range, up to 2500°C. But it is generally used in an inert atmosphere or a reducing atmosphere, othERWise a molybdenum alloy protective the sleeve is needed for protection.
