Description of Tungsten Wire
Tungsten wire (W 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 across the USA and Europe. Our high purity tungsten wire is manufactured in strict compliance with ASTM B760 and ASTM B521 standards, ensuring consistent performance and reliability for even the most demanding use cases. Whether you need 99.95% high purity tungsten wire for precision applications or alloyed tungsten wire for enhanced properties, we can tailor our products to your exact needs.
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.
