Tantalum Tube, Bar, Sheet, Strip and Wire

Tantalum grade and product requirements

Tantalum products are selected by grade, purity, alloying, product form and the governing specification. Corrosion response, fabrication behavior and high-temperature performance depend on chemistry, interstitial limits, processing history and service conditions. The material name alone does not establish suitability for a pressure, chemical-processing, medical, vacuum or elevated-temperature application.

Tube and wrought-product enquiry details

For tube, provide outside diameter, wall thickness, length, seamless or welded construction, end finish, tolerance and condition. For bar or wire, state diameter, length or coil data, straightness and surface. For sheet or strip, give thickness, width, length or coil data, flatness and edge. Include quantity, purity or grade, mechanical-property requirements, leak, pressure, ultrasonic or other testing, marking and certificate type. Add the process medium, temperature and component specification when they affect material selection.
