| Niobium is a soft, ductile metal which can be cold worked over 90 percent before annealing becomes necessary. In appearance, the metal is somewhat similar to stainless steel. The density of 8.57 gm/cc is moderate compared to the majority of the high melting point metals, being less than molybdenum at 10.2 gm/cc and only half that of tantalum at 16.6 gm/cc.
