The Best Tungsten Wire

Key Factors When Choosing Tungsten Wire

• Purity: Tungsten wire is available in various purity levels, typically ranging from 99.5% to 99.95% or higher. Higher purity generally means better performance in demanding applications, such as high-temperature furnaces or vacuum applications, where impurities can degrade performance or cause contamination. For less critical uses, a slightly lower purity might be acceptable and more cost-effective.
• Diameter and Length: Tungsten wire comes in a wide range of diameters, from very fine (e.g., fractions of a millimeter) to thicker gauges. The required diameter depends entirely on the application; for example, fine wire is used for filaments, while thicker gauges might be needed for heating elements or structural components. Length is also a practical consideration, as you'll want enough material for your project without excessive waste.
• Form and Finish: Tungsten wire can be supplied in different forms, such as spooled wire, straight rods, or custom shapes. The surface finish can also vary (e.g., black, cleaned, or polished). A clean or polished finish is often preferred for applications where surface contamination is a concern or where electrical contact is critical. Ensure the form and finish match your fabrication or installation requirements.
