Niobium-tantalum is one of many high-purity refractory alloys produced by Edgetech. As a master alloy, niobium-tantalum can be used to refine grains, harden, and improve alloy properties by enhancing properties such as ductility and machinability. Tantalum-niobium alloy is a metal alloy composed of tantalum and niobium. It is known for its high melting point, excellent corrosion resistance and good mechanical properties, making it widely used in the aerospace, chemical, electronics and medical industries.

Tantalum Niobium Alloy Wire

Available alloy forms include sheet and plate, discs, foils, rods, tubes and other shapes. Edgetech Industries produces niobium-tantalum alloys in a variety of standard Nb:Ta ratios; custom alloy compositions are also available. Tantalum-niobium alloy is an alloy based on tantalum and added with niobium. Common types of tantalum-niobium alloys include UNS R05240 Ta40Nb, Ta3Nb, Ta20Nb and Ta30Nb alloys. Edgetech offers premium quality Tantalum Niobium alloy products in the form of plates/sheets/rods/tubes/strips at competitive prices with customization options available as per specific requirements.
