Two different types of phosphate processes (at least). I need to find that link. One is oiled afterwards. The other, I believe, the oil is in the bath, or something like. It has more corrosion protection.

I like the black phosphate as well. I just used about 50 of these reassembling my frame. 7/16-14x1-1/2 Grade 8 flange bolts and locking flange nuts.
