Kupfer

Beschreibung:
Kupfer, mit der CAS-Nummer 7440-50-8, ist ein Übergangsmetall, das für seine charakteristische rötlich-braune Farbe und seine hohe Wärme- und elektrische Leitfähigkeit bekannt ist. Es ist formbar und dehnbar, was es ermöglicht, es leicht zu Drähten und Blechen zu formen. Kupfer hat einen relativ hohen Schmelz- und Siedepunkt im Vergleich zu vielen anderen Metallen, was zu seiner Stabilität in verschiedenen Anwendungen beiträgt. Es ist korrosionsbeständig, insbesondere in trockenen Umgebungen, kann jedoch anlaufen, wenn es Feuchtigkeit und Luft ausgesetzt wird, und bildet im Laufe der Zeit eine grüne Patina. Kupfer ist ein essentielles Spurenelement in biologischen Systemen und spielt eine entscheidende Rolle in verschiedenen enzymatischen Prozessen. In Bezug auf die Reaktivität kann es Verbindungen mit Nichtmetallen bilden und wird häufig in den Oxidationszuständen +1 und +2 gefunden. Kupfer wird häufig in elektrischen Leitungen, Sanitärinstallationen und als Legierungsbestandteil in Bronze und Messing verwendet, was es zu einem wichtigen Material sowohl in industriellen als auch in alltäglichen Anwendungen macht. Seine einzigartigen Eigenschaften machen es zu einem Schlüsselbestandteil vieler technologischer Fortschritte.
