We at Special Metals manufacture and supply niobium sheets in different grades and different dimensions as per requirement.
Niobium Alloy sheet is cold rolled and vacuum annealed component made from Niobium element. The commercially pure niobium products are utilized in high-end applications such as superconductors, super-coolers in particle acceleration applications.
Grades available:
There are two kinds of grades available for Niobium sheets as grade one and grade two. Grade one is called reactor-grade, and it has 0.1% max impurities. Whereas grade 2 is the commercial one that allows up to 0.2% impurities. The sheets also range in thickness from 0.006 to 0.1875 inches.
Features:
Niobium is less corrosion resistant when it is used at high temperatures. Niobium is unaffected at room temperature by most of the acids. However, it is attacked by alkaline solutions to some extent at all temperatures.
Because Niobium has a low capture cross-section for thermal neutrons, it is highly applicable in the nuclear industry. In addition, it can be anodized Niobium to a wide variety of colors that makes it attractive in jewelry industries.
Niobium is utilized in alloys, including stainless steel. It improves the strength of the alloys, specifically at the lower range of temperatures. Also, other applications are in jet engines, rockets, beams, and girders for building and oil rings.
Our Niobium sheets are widely used in different industries:
Pure Niobium sheets are manufactured through a cold rolling process. As a result, it has a chemically pure surface for different reactive applications—high-end applications such as synthetic diamond manufacturing, sputtering targets for fibre optic use, and others.
UNS R04210 grade pure Niobium sheet is utilized in nuclear reactors as well as in particle accelerators. In addition, these are utilized in the manufacturing of nickel-based superalloy and superconductors. These alloy sheets can be available in different grades and specifications and are widely used in different industries, including:
