Brass ok to use?

I inspected the impeller and it looks good. It sits and circulates inside an aluminum housing. Four stainless steel 2" X 1/4" bolts hold that housing in place.. Well, all 4 of the bolts are chewed up pretty good and pitted and just old and tired. I happen to have 4 brand new brass bolts that will do the job well, but I'm concerned about galvanic corrosion occuring between dis-similiar metals? But, then I remember brass is used a lot in the marine enviroment so I think it will be ok? :confused:So, I really just dont know:confused:

My question is brass ok to use for this application? If not can you go into detail about why? Because we all see brass being used a lot in Marine apps. Thanks :cool:
 
Brass is MUCH weaker then the stainless steel. Yes brass is used in many marine applications however lack the strength. I would visit a hardware store and get stainless steel replacement bolts. They will probably cost about .45 - .50 cents a piece. I would not want to run the risk. The $2 spent is better then the concern of a bolt breaking.
 
Thanks for the reply. Its really not a situation where strength is all that important. The brass is plenty sufficient for holding that lightweight alumunum housing in place.. My concern is the galvanic action between alum and brass? If any?
 
I'm afraid someone is mixing Brass with Bronze?
One of the components in brass is Zink!
Those screws will be gone in 'seconds'.
 
Nearly all of the impellers I have changed over the years look good. The problem with them is that they tend to take a set to them, and lose their efficiency. If you have any issues, while you have it down I would recommend a new WP kit. The bolts come with it.
