Niobium and Niobium Alloy Tube
Howah Metal could supply all kinds of size Nb and Nb Alloy Tube.
Characteristics: Niobium is a shiny, white, soft, ductile and paramagnetic metal, which takes on a bluish tinge when exposed to air at room temperatures for extended periods. It has a low density in comparison to other refractory metals, and it is corrosion resistant, exhibits superconductivity properties, and forms dielectric oxide layers.
Processing:Hot Rolled,Welded,Annealing,Extruded,Surface polished.
