MIL-C-5541 class 3 versus MIL-a-8625 type III class 2

2006

Greetings,

I am engineering student, I am designing a radiator of aluminum and wanted to consult as anticorrosive treatment but is adapted, MIL-C-5541 Class 3 versus MIL-A-8625 / MIL-PRF-8625 [⇦ this spec on DLA] Type III Class 2, and why?.

Thanks,

Lucas Jiménez Moroto

The former spec is chromate conversion coating, which leaves a thin electrically conductive film on the aluminum. The latter spec is hard coat anodizing, which is a very heavy, electrically insulating, wear resistant finish. I don't know if the former will meet your needs but I'm pretty sure the latter won't. You need to obtain the specs and read them, Lucas. They should be available free from http://assist.daps.dla.mil.
