.... However, the alloys are subject to dezincification in stagnant, acidic aqueous environments, and may fail by SCC in the presence of moist ammonia, amines, and mercury compounds. Electrical conductivity of brass is reasonably high, ranging from 56% IACS for C21000 to 28% IACS for high-zinc alloys...

... boundaries, but it may be a second phase. Dezincification is common in yellow brasses. Some corrodents selectively leach the zinc-rich phases, leaving a weak copper network. Thus, there are many stainless alloys to deal with the many corrodents that can be encountered. In every case, alloy additions were...
