Description of Tungsten Wire
Tungsten wire is a high-performance, thin, and durable form of tungsten used in applications that require resistance to extreme heat, strength, and conductivity. Tungsten (symbol W, atomic number 74) is a refractory metal with the highest melting point of any element at 3,422°C and a density of 19.25 g/cm³, which makes it highly valuable for industrial and high-temperature applications.
Application
- Lighting: Ideal for lamp filaments due to its high-temperature stability.
- Electronics: Provides conductive paths in semiconductors and circuits, handling high currents reliably.
- Medical Equipment: Used in imaging devices and radiation shielding, offering durability in sensitive applications.
- Aerospace: Essential in thermocouples for extreme temperature measurement in aircraft engines.
- Manufacturing: Employed in precision tools and EDM for its high wear resistance in part creation.
How to select Tungsten Wire
Tungsten Wire’s combination of strength, thermal resistance, and conductivity makes it a versatile material across industries such as aerospace, electronics, medical, and manufacturing. They are widely used for Lamp Filaments, X-ray Equipment, Aerospace Thermocouples, Semiconductor Circuits, and EDM Maching. Below are the key factors you should consider before using the Tungsten Wire
Diameter:
- Depending on the application, tungsten wire is available in diameters from sub-millimeter to several millimeters. Finer diameters are used in applications like medical equipment, while thicker wires are used in heating and manufacturing.
Purity:
- High-purity tungsten (99.95% or higher) is selected for applications in lighting, electronics, and aerospace where impurities could compromise performance.
Alloy Composition:
- Alloyed tungsten wires, such as W-Re or W-Cu, may be chosen for applications that benefit from enhanced ductility, conductivity, or thermal expansion properties.
Mechanical Properties:
- Tensile strength, flexibility, and ductility are key considerations, especially for thin wire in applications that require bending or coiling.
Surface Finish:
- Smooth, polished finishes may be essential for electronic applications, while a more textured finish can be suitable for industrial uses.
