ʻO ka Naval Brass C46400 he 60% keleawe, 39.2% zinc a me 0.8% tin. E like me ka mea maʻamau o nā ʻāpana keleawe me ka duplex alpha + beta structure, C46400 maikaʻi ka ikaika a me ka rigidity. Ma ka hoʻololi ʻana i ka tin no ka nui like o ka zinc, loaʻa kahi kūpaʻa kiʻekiʻe i ka wai kai. ʻO ka hoʻohui ʻana o ka tin e hāʻawi i ka alloy i kahi kūʻē kūʻokoʻa i ka dezincification, a laila e keʻakeʻa hou aku ai i ka impingement e ka wai kai ma mua o nā mahana maʻamau. Hoʻomaopopo pū ʻia ka alloy no kona kūpaʻa ʻana i ka ʻaʻahu, ka luhi, ka ʻāʻī ʻana, a me ke koʻikoʻi o ka corrosion cracking.
