Bronze fittings

[Wino24]

Hi all...I had started a thread a week or so ago asking about brass fittings in the BK and its effects on the wort. Well, I took another look at the packaging that the fitting came in and it says it's cast bronze.
So I guess now my question is: Would it be ok to put a bronze elbow in the BK? Thanks
