Product Description
High Purity 99.95% Ro 4210/4216 and the Alloys Machining Spare Parts
Description
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.
Uses of Niobium
- It is used in stainless steel alloys for cutting tools, nuclear reactors, jets, missiles, and welding rods.
- It is used in the manufacturing of MRI scanners and NMR equipment.
- Its alloys are used in making surgical implants.
- It is used for the production of stainless steel and high-temperature resistant alloys.
