Re: Can I use my boat in Salt water ?
One issue is to be sure we're defining terms - "brass" versus "bronze" is one of those tricky things, because there are different types of brass and there are different types of bronze, and in some cases, the chemical makeup of the alloys can be extremely similar - or in fact, the same, such that the same alloy has different names, depending on who you're talking to.
In particular, a short while back, I did a little research to find a "bronze" pipe for the centerboard pennant on my boat, and learned that "red brass", in America, anyhow, is another name for "gunmetal", and is considered to be both a brass and a bronze. It typically contains 85% copper, 5% tin, 5% lead, and 5% zinc, and thus is sometimes referrred to as "85-5-5-5" brass (or bronze). Based on the research I did, I concluded it was acceptable for use in my application - and I found it darn near impossible to find pipe anywhere that was made of "bronze" - although I did find pipe made of "red brass", which expressly was described as being of 85-5-5-5 content and corrosion-resistant.
