Using a sacrificial anode: In some cases, you can also cover the component with a material that serves as a sacrificial anode. So when corrosion does occur, it will only chip away the sacrificial anode and not harm the component underneath until all of the sacrificial anode has been corroded (as is the case with galvanized iron or steel which uses a thin layer of zinc as a sacrificial anode to prevent rust). I also believe you will be just fine. Combining a metal to such as one that is higher on the galvanic series can spur the corrosion of the anode while protecting the anodes cathodes that would have been at risk otherwise. Generally speaking, brass can corrode if exposed to moisture for an extended period of time, which can range from a few weeks to months or even years in more extreme climates and environments. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'remodelormove_com-medrectangle-4','ezslot_1',155,'0','0'])};__ez_fad_position('div-gpt-ad-remodelormove_com-medrectangle-4-0');In general, it is best to use stainless steel fasteners when connecting stainless steel components and bronze fasteners when connecting bronze components.
