Tantalum Tube

We supply tantalum tubes including seamless tubes and welded tubes & pipe. Welded tantalum tubes & pipes are made from tantalum strips and tantalum foil, welded tubes can be with thin wall thickness and large dimensions.

 

Tantalum tubing with OD<5mm can also be named as tantalum capillary, this is only available for pure tantalum.
