Copper and copper alloys - Cast unwrought copper products

This European Standard specifies the composition and physical properties of cast unwrought copper products (refinery shapes) in thirteen grades of copper and nine silver-bearing copper grades. The refinery shapes included are horizontally, vertically and continuously cast wire bars, cakes, billets and ingots. Wire bars, cakes and billets are intended for fabricating into wrought products; ingots are intended for alloying in wrought and cast copper alloys.
A table indicating the refinery shapes in which each copper grade is normally available is given in Annex A. Annex B gives information on the relationships between electrical resistivity and conductivity of copper.

Kupfer und Kupferlegierungen - Gegossene Rohformen aus Kupfer

Diese Europäische Norm legt die Zusammensetzung und die physikalischen Eigenschaften von gegossenen Rohformen aus Kupfer (Gussformate) für dreizehn Kupfersorten und neun silberhaltige Kupfersorten fest. Die Gussformate umfassen horizontal, vertikal und kontinuierlich gegossene Drahtbarren, Walzplatten, Rund-blöcke und Blockmetalle. Drahtbarren, Walzplatten und Rundblöcke sind zur Herstellung von Knetprodukten, Blockmetalle zum Legieren von Kupfer-Knetlegierungen und Kupfer-Gusslegierungen, vorgesehen.
Eine Tabelle in Anhang A gibt die Gussformate wieder, in denen die jeweilige Kupfersorte üb¬licherweise erhältlich ist. Anhang B beschreibt die Beziehung zwischen spezifischem elektrischen Widerstand und spezifischer elektrischer Leitfähigkeit von Kupfer.

Cuivre et alliages de cuivre - Formes brutes de coulée en cuivre

La présente Norme européenne spécifie la composition et les propriétés physiques des formes brutes de coulée en cuivre en treize nuances de cuivre et neuf nuances de cuivre à l’argent. Les formes brutes de coulée considérées sont des barres à fil, plateaux, billettes et lingots moulés par coulée continue horizontalement ou verticalement. Les barres à fil, plateaux et billettes sont destinés à être transformés en produits corroyés ; les lingots sont destinés à être transformés en alliages de cuivre corroyés et moulés.
Un tableau indiquant les formes brutes de coulée sous lesquelles chaque nuance de cuivre est normalement disponible est donné en Annexe A. L’Annexe B donne des informations sur les relations entre la résistivité électrique et la conductivité du cuivre.

Baker in bakrove zlitine - Uliti negneteni polizdelki iz bakra

Ta evropski standard določa sestavo in fizične lastnosti ulitih negnetenih izdelkov iz bakra (rafinirane oblike) v trinajstih razredih bakra in devetih razredih bakra s srebrom. Vključene rafinirane oblike so vodoravno, navpično in kontinuirno lite žične palice, plošče, kovinske palice in ingoti. Žične palice, plošče in kovinske palice so namenjene izdelovanju gnetenih izdelkov, ingoti pa so namenjeni legiranju v gnetenih in ulitih bakrovih zlitinah. Tabela, ki označuje rafinirane oblike, v katerih je običajno razpoložljiv posamezni razred bakra, je podana v dodatku A. Dodatek B navaja informacije o razmerju med električno upornostjo in prevodnostjo bakra.
