[Milsurplus] Mil Circular Material Questions

[J. Forster]

I have noticed that the Cannon style (Circular, course pitch Acme [square
thread form] screw) used in several WW II systens, like the ARB, MN-26,
RA-10, and others tend to corrode more than other connector types.

This especially applies to the matte finish WWII production, and is less
of an issue in the bright finish post-war production.

Does anyone know about the Aluminum alloy used to cast the connector
bodies? Is it perhaps high in Magnesium which is more reactive and tends
to rot in moist environments?

Also, does anyone know of a way of removing light corrosion, preferably
chemically?

Thanks,

-John
