产品代码 : ME-Nb-5N-WI
Niobium has good plasticity at room temperature, so it can be rolled, drawn, spinning, bending and other deformation processing under the condition of no heating. The raw material of producing niobium wire is usually niobium rod or niobium ingot, which is made from niobium powder by powder metallurgy or smelting. Preparation of niobium wire by melting method: niobium powder - molding - sintering - electron beam melting - blank - rolling - heat treatment - wire drawing - cleaning - inspection; Preparation of niobium wire by powder metallurgy: niobium powder - isostatic pressing - vacuum vertical melting sintering - rolling - intermediate annealing - wire drawing - cleaning - inspection.
Niobium wire is mainly used in chemical anticorrosion field, aerospace, superconductivity, atomic energy, medicine and other fields.
