Niobium Tube / Pipe
Description
Niobium is a shiny, white, soft, and ductile metal, and takes on a bluish cast when exposed to air at room temperatures for a long time. Niobium tube / pipe is made by extrusion, tube reduction, or deep drawing with the plate. And it has the characteristics of high melting point, high-density, high temperature oxidation resistance, long service life, and resistance to corrosion.
Alfa Chemistry supplies a wide range of niobium tube / pipe with competitive prices and unrivaled customer service, and we also can cut, slit, shear, or center less grind niobium tube / pipe to your exact specifications.
