- A former name for niobium
- Niobium (Greek mythology: Niobe, daughter of Tantalus), or columbium , is the chemical element with the symbol Nb and the atomic number 41. A rare, soft, grey, ductile transition metal, niobium is found in the minerals pyrochlore, the main commercial source for niobium, and columbite.
- A metal which may be added to chrome-nickel stainless steel to improve its welding and general heat-resistant qualities, by preventing carbide precipitation.
- A chemical element with the symbol Cb. Columbium is often used in high-strength, low alloy steels to increase yield and tensile strength.
- A metallic element added to steel. In small amounts (<0.05%) columbium acts as a grain refiner and improves hot working. In the range of 2-3% it serves as a stabilizer in austenitic stainless steels.
- (Chemical Symbol Cb) - see NIOBIUM.
