Gentlemen,
I was thinking a little (I do that on occasion) what happens when you
galvanize a structure containing aluminum rivets. Although the melting
temperature of aluminum is 1221°F and the zinc bath is "only" 850°F the
aluminum
may dissolve in the zinc the same way sugar dissolve in water. Even if the
rivet is solid during the process it still will disappear or reduce in size
so it can fall out.
Conclusion: Be aware it is not a good idea to galvanize hardware containing
aluminum rivets.
