Arsenical bronze is an alloy in which arsenic, as opposed to or in addition to tin or other constituent metals, is added to copper to make bronze. The use of arsenic with copper, either as the secondary constituent or with another component such as tin, results in a stronger final product and better casting behavior. Copper ore is often naturally contaminated with arsenic; hence, the term "arsenical bronze" when used in archaeology is typically only applied to alloys with an arsenic content higher than 1% by weight, in order to distinguish it from potentially accidental additions of arsenic.

  • Arsenikbrons är en legering av koppar med en liten tillsats av arsenik (upp till ca 2 %). Utmärkande egenskaper är stor hårdhet och seghet. Förekommer sparsamt i naturlig form, och utnyttjades på bronsåldern för tillverkning av diverse verktyg, främst yxor. Det sägs att en del smeder, som arbetade med detta material blev sjuka av den giftiga arseniken; ett tidigt exempel på yrkesskada.
  • Le bronze arsénié est un alliage dans lequel de l’arsenic est ajouté au cuivre à la place, ou en plus de l’étain ou d’autres éléments métalliques d’addition, pour former du bronze. L’utilisation d’arsenic avec le cuivre, en tant qu’élément secondaire d’alliage ou en compagnie d’un autre composant tel que l’étain, donne un alliage à la fois plus résistant et présentant un meilleur comportement au coulage.
  • Il bronzo arsenicale è una lega in cui l'arsenico viene aggiunto al rame come contrapposto ad, o in aggiunta ad altri metalli costituenti. L'uso di arsenico nel bronzo, come costituente secondario o insieme ad altro componente come lo stagno, dà come risultato un prodotto finale più robusto. Poiché il minerale dal quale si ricava il rame è spesso contaminato naturalmente dall'arsenico, il termine "bronzo arsenicale" viene applicato generalmente soltanto a leghe che contengono abbastanza arsenico (superiore al 2-3%) da suggerire una sua inclusione intenzionale.
