I love the look and feel of my Code 1 with brass spikes, but it seems to be damaging the nickel in the hub. Just wondering if anybody else is experiencing this. ---

It’s possible you’re seeing [galvanic corrosion](https://http) where one metal is having a direct effect on the other. ---

The Nickel was getting a white buildup which was eating through it, bare aluminum is exposed in some spots. The brass is turning green which is normal for brass. ---

Strange, I’m aware of the green patina on brass, but unsure about the white corrosion. Pics would be helpful. ---

Nickel oxide alone could also show a green color just like copper. However, if even the copper part of the brass is corroding, then everything would regardless of being in contact w another metal or not. I havent seen anything of either brass or nickel literally turning green in a typical indoor environment. I n my experience that only happens when you soak it in mud and seawater. You could still try to polish the area in contact w the spikes down to raw aluminum, andwhut ---

What kind of environment do your yoyos live in? Is it damp or humid? These sort of reactions almost never take place in a dry environment. I have a couple dozen nickel yoyos and some of them have brass in contact with the nickel. but I have yet to see the chemical reactions you are experiencing. More information, please! db ---
