"and the associated probability of hydrogen imbrittlement can reduce the ductility and lifespan of the tubing." QUOTE

The hydrogen embrittlement is the reason for the 'baking-out', process after plating.

Also may be of interest:

(1) The last, and final step (copper/nickel/chrome) is only about 5 microns thick.

(2) contrary to popular belief, plating is porous, therefor a good protectant is a 'must'. (eg wax or oil)
