Brûns is in soarte en groep fan koper-basearre alloy mei Tin as de wichtichste alloy elemint. De hurdens en sterkte fan brûns ferheegje mei in tanimming fan Tin-ynhâld. De ductility wurdt ek fermindere mei de tanimming fan tin persintaazje boppe 5. As aluminium wurdt ek tafoege (4 oan 11%), de resultearjende alloy wurdt neamd aluminium brûns, dat hat in oanmerklik hegere corrosie ferset. Brûnzen binne relatyf djoer yn ferliking mei koperen fanwegen de oanwêzigens fan tin dat in djoer metaal is.
Lykas in protte oare alloys, koper en koper-basearre alloys kinne wurde foarme yn tige komplekse dielen, wêrtroch't se ideaal foar it sân casting enynvestearrings casting proses. Konstante kostenfluktuaasjes kinne dizze materialen tige priisgefoel meitsje, wêrtroch ôffal tige kostber wurdt, foaral as jo beskôgjeCNC ferwurkjenen / of smeden as in produksjeproses om jo diel te produsearjen. Suver koper wurdt normaal net getten.
