Niobium

Niobium, chemical symbol NB, atomic order is 41, which is a transition metal element.Single quality is a shiny gray metal. High -purity Niobium metal has a high ductility, but it will harden up with the increase in impurities. The section of the hot neutron capture is very low, so it is quite useful in the nuclear industry. Brazil and Canada have the largest roasted greenstone minerals. The two countries discovered these minerals in the 1950s, and they are still the largest producing countries of sperm ines. The world's largest minerals are located in one of the carbonate in Arassa, Manasglas, Brazil. Invasive rocks. The output of the above two mines accounts for 75%of the world's total output. The third -largest mine is located near Sagina, Quebec, Canada, with an output of 7%. As a micro -alloy element, adding the structure of the steel does not change the structure of the iron, but is combined with the carbon#nitrogen#sulfur in the steel to change the micro -structure of the steel. The reinforcement effect on steel is mainly the fine crystal reinforcement and diffuse reinforcement. The carbon nitrogen in the steel and the carbon nitrogen in the steel generate stable carbides and carbon nitride. It can also disperse carbides and form fine -crystallized steel.
 
The main ingredient of the FerroNiobium is the iron and Niobium. It also contains impurities such as aluminum, silicon, carbon, sulfur, phosphorus. According to the alloy's tadpoles, it is divided into FENB50, FENB60, and fenb70.
Tie iron is a vital raw material in the production of steel. The world's largest iron supplier is the CBMM of Brazil. Dometar integrates high -quality resources through various channels. And iron powder. 0-5mm, 10-50mm, 10-100mm, if you need to be iron, please contact our sales manager.
