25 percent of any of the following elements: aluminum, chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, or vanadium; Metal alloys consisting of nickel, iron-nickel, and cobalt base alloys containing a total of other alloying metals (except iron) in excess of 10 percent; Titanium and titanium alloys; or Zirconium and zirconium base alloys4 The specialty metals definition includes an exception for certain qualifying countries, including most members of NATO.

In 1809, William Hyde Wollaston, a British chemist, analyzed both columbite and tantalite mineral specimens and claimed that columbium and tantalum were the same element [14,15].

Between 1975 and 1978, copper and cobalt production had fallen by 25%, the production of tin and strategically important columbium and tantalum ran below capacity, and the mining of manganese stopped altogether due to collapsing transport systems and lack of supplies, parts, and technicians.

These declines dampened demand for bauxite and alumina used in aluminum production, and for ores of tantalum, zinc, columbium, and other metals used in steel alloying.

While binders such as molybdenum, columbium, and tantalum are used as replacements for cobalt, they are not considered as effective.

The major product segments analyzed are Non-Ferrous Alloys (Aluminum, Magnesium, Titanium, and Zirconium), Refractory Metal Alloys (Molybdenum, Tungsten, Columbium, and Tantalum), Platinum Group Metals (Platinum, Palladium, Rhodium, Ruthenium, and Iridium), and Special Alloys & Superalloys.
