2) brass will not corrode to the point of its structural integrity being compromised..... it is fairly corrosion resistant, hell, its used heavily in salt water environments for a reason. 1) why does the brass need to be shiny? (Steel, on the other hand, does rust because it contains iron.) Bronze. 2005. 2. I have some damage in a 27 year old float that has been siting in a lawnmower carb all that time.. The owner filed a suit against the insurer, and lost. Parting Corrosion Dezincification. On the strength of the contract’s “corrosion exclusion,” the owner’s insurance company refused to pay for the loss. I was only disappointed that the article didn't seem to mention 321 or 347 stainless. Answer: Nice work, you have made an observation that the average boater would never have made. Setting the legal drama aside, the anecdote is a reminder to builders and service yards to beware of brass when selecting or replacing below-the-waterline marine hardware. Copper does not rust – as rust is iron oxide and only corrosion of iron can create rust Then again after 40 years maybe its just due for a new $12 float. The dezincification corrosion was due to the high concentration of internal deposits, hot water temperature, water pH and chloride content, possible stagnant or low flow conditions early in the fitting life, and the use of a brass material susceptible to this form of corrosion (copper alloy 36000, leaded brass). They used to be a "gun metal" bronze in the oldie days. If completely submerged in a clean stream or lake that does not have a lot of offending materials like a low pH or sulfides and etc, it will probably last for many years and only slowly grow a corrosion layer. Brass does in fact corrode -- it’s just not typically referred to as “rust” in conversation. However, copper can form a blue-green patina on its surface when exposed to oxygen over time. For steels we use both salt spray and mostly humidity chamber tests but am not too sure how applicable they are for brass. There's a PDF document you can view or download. A. Accelerated Corrosion Testing for Brass May 7, 2014-- this entry appended to this thread by editor in lieu of spawning a duplicative thread. Brass and Bronze have a relatively high zinc content. Here's an interesting website with some good information about stainless steel in salt water. 3. There is no good answer to your question as it will depend on the quality of the water. Brass alloys with more than 15% zinc, such as Admiralty, aluminum brass, Muntz metal, naval brass, and manganese bronze, were susceptible to a specific form of corrosion in seawater termed dezincification (or parting corrosion). It has a negligible amount of iron. It's strong and ductile and used for everything from binnacle fittings, to instruments, to naval gun parts. Q. What tests are recommended for accelerated corrosion testing of Brass components? Brass does not rust, only iron-bearing materials will rust. They are not recommended for plumbing applications below water or in saltwater situations. Hence why they have Aluminium brass and Admiralty brass and all those other brass alloys for salt water service. Bronze does not rust for the same reason as aluminum. Unlike iron, brass does not form weak, flaky rust when it corrodes. Brass will corrode however. So, brass can’t "rust" by the standards of Definition #1 above. It has a negligible amount of iron in it. You are quite correct, aluminum and brass should never be in direct contact with one another in the marine environment. Brass does not rust for the same reason as aluminum. Brass. This is a plain tin bronze which machines and poliishes very well, has a handsome red gold sheen and has good corrosion resistance to salt water - spray or immersion. This doesn’t mean metals besides steel and straight-up iron can’t corrode, too. The mix is a guaranteed prescription for corrosion, and in the case of fuel fittings, probable breakage of either the tank or the fitting when you attempt to disassemble the … This layer acts as a barrier that prevents more air and moisture from contacting the brass substrate, thus halting further corrosion. Therefore, no iron oxide, or rust, can form. Copper, Brass, Bronze, or naval bronze follow. Instead, a firm and durable patina layer appears on the surface of brass when exposed to air and moisture.
