Niobium - Tantalum / Tube

Description

Niobium is a rare, soft, gray-white metal with a high ductility at room temperature. Tantalum is ductile and highly resistant to acid corrosion. It has a high melting point and is a good heat and electricity conductor, and it is frequently alloyed with Niobium for applications requiring heat-resisting and combustion equipment. Niobium-tantalum (Ni-Ta) alloy is an alloy based on niobium added with the tantalum element.

Alfa Chemistry provides high-quality niobium-tantalum tubes at a competitive price, which can be used in scientific research or industrial production.
