TA0006 Tantalum Wire

Descriptions of Tantalum Wiretantalum-wires

Tantalum Wire is corrosion resistant and has good thermal conductivity. Tantalum Wire can be used in the manufacture of heating elements, vacuum tubes, and other high-temperature parts. Tantalum Wire can take hydrogen, oxygen, and nitrogen away from the atmosphere and is the ideal product for vacuum applications in the lighting industry.

When I got this product, I initially thought that this was going to be hard to work with and the wire would be too stiff. I am happy to say I thought wrong! This wire is VERY easy to work with and bend to whatever shape you need. I use this to create polymer clay figures and it's exactly what I was looking for. Super easy to cut as well.
