Description of Tungsten Rod and Bar
Tungsten rods and bars are solid, high-density forms of tungsten known for their exceptional strength, high melting point (3,422°C), and resistance to corrosion and wear. Available in both pure tungsten and tungsten alloys, they are essential for applications that require durability under extreme temperatures, such as aerospace, defense, and high-temperature furnaces. These rods and bars are typically produced through powder metallurgy, rolling, or forging to achieve precise dimensions and desired mechanical properties. Tungsten rods and bars are widely used in radiation shielding, tooling, electrodes, and industrial machinery, where they provide stability and performance in demanding conditions.
Application
Tungsten rods and bars are used in aerospace components, radiation shielding, high-temperature furnaces, and electrical contacts. They are also essential in manufacturing tooling, machining equipment, and medical devices due to their high strength, heat resistance, and durability.
How to select Tungsten Rod and Bar
When selecting tungsten rods and bars, consider the following key factors:
- Purity: Choose high-purity tungsten (99.95% or higher) for applications requiring maximum strength and heat resistance.
- Size and Dimensions: Select the appropriate diameter and length based on your application needs, with thicker rods for structural components and thinner ones for precision use.
- Alloy Composition: Tungsten alloys (e.g., W-Ni-Fe, W-Cu) may be needed for enhanced machinability or specific properties like corrosion resistance.
- Mechanical Properties: Ensure the material meets the required tensile strength, hardness, and elongation for your application.
- Surface Finish: Depending on the application, a polished or coated surface may be required to ensure durability and functionality.
