How To Use Columbium In A Sentence

In steel alloyed with molybdenum, manganese and columbium, which is use for these pipe-lines, molybdenum raises both strength and toughness.
For high strength grades, aluminum, vanadium, or columbium may be used for grain refinement.
These minerals are the principal sources of columbium (commonly called niobium), tantalum and molybdenum metals. Rhenium
Most alloying elements, such as chromium, columbium, copper, iron, manganese, molybdenum, tantalum, and vanadium stabilize the phase to the extent that a mixed - phase or an entirely phase alloy can persist down to room temperature.
The refractory metals include niobium (also known as columbium), tantalum, molybdenum, tungsten, and rhenium.

The gas tungsten arc welding process is used for the pure columbium and for the lower strength commercial alloys.
To eliminate the intergranular corrosion, it is necessary either to reduce carbon to very low levels, or to add titanium and columbium to tie up the carbon and nitrogen.
Columbium (also called niobium), like vanadium, is generally considered to increase the hardenability of steel. CR4 - Recent Forum Threads and Blog Entries
Coltan is a contraction of columbium and tantalum; it's found in 3 billion year old mud and without it much of our modern technology could not be made.
