99.5% Pure Niobium and Niobium Alloy Rods, Bars for
High-temperature Resistant Area
Description
Niobium Rod / Bar is widely used in chemical, electronic, aerospace
and other fields for its properties of high melting point,
corrosion resistance and good cold working performance.
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. The metal starts to oxidize in air at 200°C, and when
processed at even moderate temperatures must be placed in a
protective atmosphere.
High-purity Niobium Rod & Niobium Bar can be bought at Stanford
Advanced Materials (SAM). With extensive experience in the
manufacture and sale of niobium products, SAM offers customers
high-quality Nb Rod & Nb Bar at competitive prices. We are also
able to customize this product according to various specifications.
Niobium is used as an alloying agent and for jewelry, but perhaps
its most interesting applications are in the field of
superconductivity. Superconductive wire can be made from an alloy
of niobium and titanium which can then be used to make
superconductive magnets. Other alloys of niobium, such as those
with tin and aluminum, are superconductive as well. Pure niobium is
itself a superconductor when it is cooled below 9.25 K (-442.75°F).
Superconductive niobium cavities are at the heart of a machine
built at the Thomas Jefferson National Accelerator Facility. This
machine, called an electron accelerator, is used by scientists to
study the quark structure of matter. The accelerator's 338 niobium
cavities are bathed in liquid helium and accelerate electrons to
nearly the speed of light.
