CTIA Tungsten Wire Specifications
As a tungsten wire manufacturer, CTIA offers a comprehensive specification system covering diameter, tolerance, length forms, surface conditions, and application requirements. This integrated approach ensures reliable performance across demanding environments such as high temperature, vacuum, electron emission, and industrial heating.
Diameter is a core parameter in tungsten wire classification, with sizes spanning from ultra-fine to coarse grades across multiple application levels, enabling precise matching to different functional requirements.
Length forms are flexible to accommodate various processing needs. Standard cut lengths typically include 100 mm, 300 mm, and 1000 mm, while coil forms such as 10 m, 100 m, or longer are available for continuous operation and automated production.
CTIA supplies tungsten wire with purity levels up to ≥99.95%, with lower grades available for general industrial use; higher purity contributes to improved high-temperature strength, lower vapor pressure, and enhanced thermal and electrical conductivity.
Surface condition is a key factor influencing performance, especially in vacuum and electron emission applications. CTIA mainly supplies black tungsten wire and cleaned tungsten wire. Black tungsten wire retains a lubricated surface from drawing, making it suitable for further processing, while cleaned tungsten wire is treated to remove surface residues, enhancing emission stability and overall reliability in vacuum environments.
CTIA also provides shaped tungsten wire tailored to application requirements, including coiled wire, double-coiled wire, bent wire, and customized geometries. These products are typically formed from wire in the φ0.02–1.0 mm range, depending on the forming process and end use, and are manufactured through controlled forming techniques to achieve precise structures, meeting specific requirements for geometry and heat distribution in lighting filaments, electron emission components, and heating elements.
These diameter specifications cover the full application range, from precision electronics to high-temperature industrial support. For ultra-fine and fine tungsten wire, diameter tolerances can be controlled within ±0.001 mm to ensure stability in precision applications; for medium and coarse wires, tolerances are typically maintained within ±0.01 mm to meet the requirements of industrial processing and high-temperature service.
The specification of CTIA’s tungsten wire covers the full diameter range, from ultra-fine to coarse diameter wires. Supported by flexible options in length, surface condition, and application requirements, CTIA delivers reliable and customizable solutions for demanding applications in lighting, electronics, vacuum systems, precision manufacturing, and high-temperature structures.
