Description of 99.99% Pure Tantalum Tube
Tantalum tubes, due to their high melting point (2996°C), corrosion resistance, and biocompatibility, are widely used in chemical equipment, thermocouple protection tubes, capacitor positive leads, and medical implant materials. In the field of high-temperature measurement, tantalum tubes can be used as outer protective tubes for tungsten-rhenium thermocouples, withstanding vacuum environments up to 2300°C.
YIWU YITECH has been deeply engaged in the field of high-purity tantalum materials for many years. Our core advantages lie in our strict adherence to ASTM B365-22 and GB/T 3629-2017 standards, which allow us to stably control the purity of tantalum tubes at 99.99%, reduce impurity content to the parts per billion (ppb) level, and achieve extremely high dimensional accuracy – with a diameter tolerance of ±0.003mm and a wall thickness deviation of ±0.005mm. We also offer the ability to customize both seamless and welded tubes, and can adjust the size and surface roughness (Ra≤0.8μm) as needed.
