Are you sure the specs are metallic? That would be interesting. I had theorized many of these were gummy, silicon-like deposits of adhesive combined with anti-corrosive salts. Neither one is particularly helpful.
The things I do for Science...

Just confirmed that there is a electrical potential between the new block and the rad when disconnected from everything, which pretty solidly shows the possibility for corrosion. The way metal works, if it's "possible", it -will happen-, only the rate is in question.

Anyway, on the copper block image, the white specs are likely on the magnifying glass. Then you can see the rubberized stickdown section for the sheath. It makes both the gear-like pattern on the outside as well as the dark black bar across the center of the fins. The corrosion on the block is evident in the brown both on the fins as well as in the well around the fins. In a properly-running system, the block should be pretty, bright, shiny copper. Not this brown {censored}.

Inside the remaining not-opened radiator, even just in the barb fittings, there is substantial oxide, making the entirety of the inside of the barb white, including several nodules of growth.

Any anti-corrosive salts would need to be in solution, so any that have formed visible crystals are Very Bad. It could be a result of super-saturation due to evaporation of coolant, I admit, however that would not explain the pictured corrosion of the block.
