Best Alloy for salt water (Sea water)
Best Alloy for salt water (Sea water)
(OP)
Hi Guys.
I am interested in finding the most suitable material for a sea water application. Because we would like to conduct heat Aluminium is the first choice. As the parts will be die casted I set my sites on A360. However I cannot find any good information regarding how this material will perform under emersion in sea water.
Can anyone help with this?
Thanks
In advance

How has the seawater been treated? chlorination? filtration?

If you must use a die cast Al part, it will need to be properly surface treated in order to have sufficient corrosion resistance. This usually means pretreatment + primer + topcoat + sacrificial anode (cathodic protection). Here is an excellent description of the development of an outboard motor transmission housing including all of the above mentioned details:
