1.2*0.2 Pure Nickel Capillary Tubing – Superior Conductivity for Electrical Components

Pure Nickel Capillary Tubing – Superior Conductivity for Electrical Components
When it comes to electrical components, performance is all about precision and reliability — and that starts with the materials. At our company, we’ve worked with customers in electronics, energy, and instrumentation, and one thing is clear: pure nickel capillary tubing is becoming a go-to choice for engineers who need top-tier conductivity and durability in compact systems.

Why Pure Nickel?
We typically use Nickel 200 or Nickel 201, known for their high nickel content (99.6%+), excellent electrical and thermal conductivity, and strong resistance to corrosion. Unlike other materials, pure nickel maintains its integrity even in harsh or high-heat environments, which is critical for today’s advanced electronics.
Some key advantages:
High electrical conductivity
Corrosion resistance — ideal for humid or chemically active environments
Non-magnetic and stable in a wide temperature range
Great formability and weldability, perfect for precision assemblies

Where Are These Tubes Used?
We see pure nickel capillary tubes used in a wide range of electrical and electronic systems, including:
Battery management systems (BMS) – for safe, low-resistance pathways
Connectors and terminals in harsh environments
High-reliability signal transmission in aerospace or military devices
Micro-electronic sensors and probe components
Electromagnetic shielding and grounding applications
These tubes are also used as lead tubes for thermocouples and current-carrying elements in ultra-compact systems.

What's Driving Demand?
Several market trends are pushing pure nickel tubing to the forefront:
Miniaturization of electronics – As devices get smaller, materials must handle the same power in tighter spaces.
Electrification of everything – From EVs to IoT, modern systems rely on stable, low-loss electrical pathways.
Demand for reliability – In aerospace, medical, or industrial electronics, failure is not an option. Nickel offers long-term stability.
Sustainability focus – Nickel is fully recyclable, and its long service life reduces waste in high-end systems.
In short, engineers and designers are looking for performance over price — and pure nickel delivers.
