Tungsten Coil

Tungsten Coil Description

A tungsten coil is formed by winding tungsten wire into a spiral shape. The coil geometry and wire dimensions depend on the required design. For custom orders, buyers can provide their specifications or a technical drawing for review before production.

Material selection and processing

We start by selecting high-purity tungsten materials and removing impurities. Next, the materials are pressed into wires and undergo high-precision wire drawing using specialized machines. Following this, the wires are subjected to high-temperature treatment, cutting, and polishing. Finally, we conduct rigorous quality and performance testing.

Characteristics

• High melting point: Tungsten has a melting point of approximately 3,422°C, making it suitable for applications requiring resistance to very high temperatures.
• Low vapor pressure at high temperatures: Tungsten is used in certain high-temperature and vacuum applications where low vapor pressure is important.
• Formable into coil geometries: Tungsten wire can be wound into different coil shapes to meet specified design and dimensional requirements.

Tungsten Coil Filament Application

Tungsten coils are used in applications that require tungsten wire in a coiled configuration. The appropriate coil design depends on the operating temperature, installation method, and dimensional requirements.

Potential applications include:

• Lighting components: Tungsten wire is used as a filament material in incandescent and halogen lamps. The coil design depends on the lamp structure and operating requirements.
• Electronic devices: Tungsten wire may be used in specific electron-emitting components, depending on the device design.
• High-temperature equipment: Tungsten components are used in selected high-temperature applications where their thermal properties meet the operating requirements.

The suitability of a particular tungsten coil should be confirmed against the equipment design and service conditions before ordering.
