Unsticking corroded jib track

[pipnosis]

The jib lead tracks on my boat are in a poor state and need replacing. The cars themselves, however, are heavy duty Garhauer ones and are in great shape. The problem is that the cars are aluminum and the old track is bronze, and the two have more or less welded themselves together.

Any ideas for getting them apart?

I am in the process of waiting for CorrosionX to do its work, but it's been a few days and no sign of success. I'd rather not buy new cars; they are $350 each.

And which metal is less noble?

Because you see the less noble one has lost a lot of its mass ...

Start with plenty of hot water and punch the cars ever so slightly with a rubber mallet. As soon as the stuff gets unstuck you will be able to unslide the cars and clean them thoroughly in the garage. But they may be gone.

Was a very bad idea to mix bronze with aluminum.

Try Moovit by Lloyds. Once you can get it to move a bit by tapping with a plastic hammers it will free up. I have had good luck with this stuff in frozen furler cars.
