Seamless Nickel Capillary Tubes – Ideal for Semiconductor & Vacuum Systems

These tubes are crafted from high-purity nickel (typically Nickel 200 or 201) and drawn down to incredibly small diameters with tight tolerances. The seamless structure means there are no weak points or welds, which is critical in environments that demand leak-free performance and absolute consistency.

Here’s what makes them stand out:
Excellent corrosion resistance, especially in vacuum and reactive gas environments
High thermal and electrical conductivity
Non-magnetic and low outgassing, ideal for ultra-high vacuum (UHV) systems
Outstanding purity, which prevents contamination of sensitive processes

Perfect for Semiconductor & Vacuum Systems
Semiconductor fabrication is all about precision at the microscopic level. Contaminants, leaks, or thermal instability can cause massive defects in a production line. That’s why our customers in chip manufacturing and cleanroom environments rely on seamless nickel capillaries for:
Gas delivery lines
Chemical vapor deposition (CVD) equipment
Plasma etching systems
Sensor and thermocouple protection
Leak-proof vacuum feedthroughs
In vacuum technology, especially UHV and cryogenic applications, the benefits are just as clear. These tubes perform reliably under:
Extreme negative pressures
High thermal cycling
Exposure to reactive or corrosive gases

What’s Driving Market Demand?
We're seeing a sharp rise in demand, and here’s why:
Semiconductor industry growth: With AI, 5G, and electric vehicles booming, chip production is expanding rapidly—and so is the need for contamination-free systems.
Miniaturization: As devices shrink, tolerances tighten. Capillary tubes are now used in microfluidic and nano-scale delivery systems.
Vacuum tech innovation: From space science to advanced optics, vacuum systems are going deeper, cleaner, and more complex. That requires better materials.
Global clean energy shift: Nickel’s chemical resistance makes it a top choice in hydrogen energy and fuel cell research too.
