I-Naval Brass C46400 ngokwegama yakhiwe ngethusi elingu-60%, i-zinc elingu-39.2% kanye nethini elingu-0.8%. Njengoba kuvamile kuma-alloys ethusi anesakhiwo se-duplex alpha + beta, i-C46400 inamandla amahle nokuqina. Ngokufaka ithini esikhundleni senani elilinganayo le-zinc, kutholakala ukumelana nokugqwala okuphezulu emanzini olwandle. Ukwengezwa kwethini futhi kunikeza ingxubevange ukumelana ngokwemvelo nokukhishwa kwezinyosi, ngaleyo ndlela kuvimbele nakakhulu ukufakwa kwamanzi olwandle ezingeni lokushisa elingaphezu kokuvamile. I-alloy nayo iyaziwa ngokumelana kwayo nokuguga, ukukhathala, ukugabha, kanye nokuqhekeka kokugqwala kwengcindezi.
