Product Code : ME-Ni-5N-RI
Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950.
Niobium Rings can be customized in width, thickness, and ring diameter. Niobium rings may have a custom shape hole and may be open or closed. ATT specializes in producing high purity uniform shaped Niobium rings. ATT offers custom rings with annealed or hard tempers and will meet most of the common Milspec or ASTM standards. Niobium rings are hollow, circular pieces of metal and can be produced in custom sizes. In addition to standard alloys, ATT also specializes in corrosion resistant alloys, high temperature applications, and custom shapes and forms including custom inside and outside dimensions and threading. ATT also produces Niobium as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Niobium rings can be used as components in several applications.
ATT is a professional supplier of Niobium Ring, We also produce disc, granules, ingot, pellets, pieces, powder , rod, wire, sputtering target and in numerous other forms and custom shapes. Other shapes are available by request.
Please contact us if you need customized services. We will contact you with the price and availability in 24 hours.
