In a more general way, people like brass because it looks like gold but is much cheaper. It is weather resistant, and while it tarnishes or aquires a patina to a brownish color, that color is not unattractive either. In fact, "antique brass" color is a recognized finish color for things like architectural metalwork.
It holds up well in a marine environment, although it requires polishing if you want to keep it bright. It also seems a more "friendly" color than chrome or stainless steel and can have an old fashioned charm.
It is fairly easy to cast, and as mentioned above, easily machined types are available. Although brass alloyed with lead should not be used for use with drinking water these days. People should be careful as due to the health effects of lead. Copper oxide is not good for you either, but this is less of a problem apparently. |
