Materials
.
.
 

• Pure Tungsten
  
  With a purity of 99.95% or higher, pure tungsten offers excellent strength, high melting point, and reliability under extreme temperatures. It's widely used in semiconductors, lighting, and medical applications.
   

• Doped Tungsten
  
  Enhanced with additives for specialized performance:

  • Thoriated Tungsten: High electron emission, ideal for welding and discharge applications.
  • Lanthanated Tungsten: Superior creep resistance for high-temperature environments.
  • Potassium-Doped Tungsten Wire (W-K)
    W-K wire is enhanced with trace amounts of potassium, creating an elongated interlocking grain structure that provides exceptional non-sag properties after re-crystallization. This makes it ideal for high-temperature applications like filaments and heating elements. Available in diameters ranging from less than 0.001 inches to 0.250 inches, W-K wire offers excellent performance and durability under extreme conditions.

• Tungsten-Molybdenum Alloy (W-Mo)
  
  It combines high thermal stability with oxidation resistance, making it perfect for aerospace and furnace applications.

 

Our Advantages
.
.

 

Yolo custom-produces tungsten wire and tungsten rods for the electro-optical and vacuum tube industries, using high-quality, stable tungsten raw materials. The wire and rods are designed to meet specific customer requirements for thermal conductivity, creep resistance, durability, light output, electron emission, reliability, and mechanical stability. These products are mainly used in the manufacturing of electro-optical sources, vacuum devices, various heating elements, environmental protection equipment, medical devices, and semiconductors

 

• High-Temperature Performance
  YOLO tungsten wire is tailored to meet diverse high-temperature performance requirements based on specific customer applications. This ensures its suitability for a wide range of demanding environments.

• Diameter Consistency
  YOLO guarantees excellent uniformity across the tungsten wire. For any continuous 200 mm section, the weight difference does not exceed 0.5% of the nominal specification.

• Straightness

  • For straightened tungsten wire with a diameter less than 100 μm, the natural droop height of any 500 mm section is ≥450 mm.
  • For wire with a diameter ≥100 μm, the arc height of any 100 mm chord length is ≤10 mm.
  • The wire's surface is smooth and free of defects such as cracks, burrs, scratches, dents, unevenness, or oil contamination.

• Winding Performance
  During the winding process, the tungsten wire maintains excellent integrity and does not crack or break, ensuring high reliability for customer applications.

Tungsten Wire Processing
.
.
 

· Flaw Detection

 

 

YOLO implements thorough inspections at every production stage, ensuring 100% flaw detection for wire ends as thin as 0.39 mm to identify cracks. The grading system includes Grade A (e.g., 2 crack points per 100 meters), B, and C. Any wire below Grade C is discarded, as more cracks increase the likelihood of yarn breakage during processing.



 

·  Drawing Process
 

 

 

YOLO uses advanced drawing equipment, including a German-imported rolling mill that deeply processes the rod core to ensure a more uniform internal structure. Unlike traditional surface-only processing methods, this advanced technology improves product consistency and quality.
