Li-castings tsa koporo le li-bronze ka bobeli ke li-alloy castings tse entsoeng ka koporo tse ka etsoangho lahla lehlabathele mekhoa ea ho kenya lichelete. Brass ke motsoako o entsoeng ka koporo le zinki. Brass e entsoeng ka koporo le zinki e bitsoa koporo e tloaelehileng. Haeba e le mefuta e fapaneng ea li-alloys e entsoeng ka likarolo tse fetang tse peli, e bitsoa koporo e khethehileng. Brass ke motsoako oa koporo o nang le zinki e le ntho e ka sehloohong. Ha lihlahisoa tsa zinki li ntse li eketseha, matla le polasetiki ea alloy li eketseha haholo, empa thepa ea mochine e tla fokotseha haholo ka mor'a ho feta 47%, kahoo zinki tsa koporo li ka tlaase ho 47%. Ho phaella ho zinki, koporo e entsoeng hangata e na le lisebelisoa tsa alloying tse kang silicon, manganese, aluminium le lead.

Cast brass e na le thepa e phahameng ea mochini ho feta boronse, empa theko e tlase ho feta boronse. Cast brass hangata e sebelisoa molemong oa ho jara lihlahla, lihlahla, likere le likarolo tse ling tse manganga le li-valve le likarolo tse ling tse sa jeng. Brass e na le khanyetso e matla ea ho apara.
