Advanced Material Insights & Engineering Excellence
In the realm of high-precision engineering, the Capillary Oxygen-Free Copper Tube stands as a critical component that bridges the gap between material purity and mechanical functionality. As a leading exporter, Sichuan Kepai New Material understands that "Oxygen-Free" is not just a label—it is a guarantee of performance in environments where hydrogen embrittlement is a fatal risk.
Standard copper contains residual oxygen, usually in the form of cuprous oxide. When exposed to hydrogen at elevated temperatures, this oxygen reacts to form water vapor, creating internal pressure that leads to cracks. Our C10100 and C10200 grade capillary tubes are processed in a strictly controlled vacuum or reducing atmosphere, ensuring oxygen levels are kept below 0.001%. This results in superior electrical conductivity (min 100% IACS) and exceptional thermal management capabilities.

The global demand for capillary oxygen-free copper tubes has surged by 15% annually, driven by the miniaturization of electronic components and the rapid expansion of the New Energy Vehicle (NEV) market. Procurement directors from Europe and North America are increasingly looking for "Information Gain" regarding the trace element control in these alloys. Sichuan Kepai addresses this by providing comprehensive spectral analysis for every batch, ensuring that impurities like phosphorus, sulfur, and lead are kept within sub-ppm levels.
Our strategic position as a top-tier exporter allows us to offer macroscopic industry solutions. We don't just supply tubes; we provide Technical Route Maps for thermal exchangers, vacuum interrupters, and medical cryogenic applications. This consultative approach ensures that our clients achieve optimized cost-to-performance ratios.
