Austria's niobium euro series, launched in 2003, was the first bimetallic coinage to use niobium as a core material anywhere in the world — the Austrian Mint held exclusive rights to the process for years afterward. The 2007 aviation issue coincided with the centenary of the first powered flights in Austria, a milestone in a country that produced several pioneering aeronautical engineers largely overshadowed by the Wright brothers' dominance of the popular record.
The niobium centre changes color depending on the oxide layer applied during minting, making each annual issue visually distinct. That color — a deliberate production variable, not a finishing step — cannot be replicated after striking.
