Properties of Nb521 niobium-tungsten alloy

Tungsten is an effective strengthening element for niobium, but with the increase of tungsten addition, the plasticity and brittle transition temperature of the alloy will increase

ASTM B348 Titanium Frequently Asked Questions

1. What is ASTM B348? ASTM B348 is organized by ASTM International (formerly the American Society for Testing and Materials). It outlines requirements for hot or cold worked bars a

Niobium Coinage Applications

In numismatics, niobium is sometimes used as a precious metal on commemorative coins along with gold and silver. For example, Austria has produced a series of silver niobium euro c

Niobium Steel Applications

Among the various microalloying elements of steel, scrap niobium is the most effective microalloying element. The role of niobium is so great that an abundance of niobium atoms in

Niobium for medical applications

Niobium also plays an important role in surgical medicine, not only in the manufacture of medical devices, but also as a "bio-adaptive material". For example, niobium she

Niobium-Based Alloys

Alloy C-103 was a niobium alloy developed in the early 1960s by Wachovia and Boeing. As a result of the Cold War and Space Race, several U.S. companies such as DuPont, Union Carbid

Niobium high temperature alloy applications

A large part of the world's niobium is used to produce nickel-, chromium- and iron-based high-temperature alloys, either as pure metal or in the form of high-purity ferroniobiu

Applications of niobium superconductivity

It was discovered a long time ago that once the temperature is lowered to near absolute zero, the chemical properties of some substances suddenly change and they become "super

Niobium distribution

Niobium is estimated to have an abundance of 20 parts per million in the Earth's crust, ranking 33rd among all elements. Some scientists believe that niobium is more abundant t

Niobium Compounds

Niobium is very similar to tantalum and zirconium in many ways. It reacts with fluorine at room temperature, with chlorine and hydrogen at 200°C, and with nitrogen at 400°C

Production of niobium

Niobium metal can be produced by electrolysis of molten potassium niobium heptafluoride, or by reduction of potassium niobium heptafluoride with sodium metal or niobium pentoxide w

Niobium for the nuclear industry

Niobium (niobium) is a chemical element. Chemical symbol Nb, atomic number 41, atomic weight 92.90638, belongs to the Periodic System V B. 1801 British C. Hachette from columbite s
