Why is it you want a Metal Can IC? The reason that they're hard to find is that they aren't really any better than the silicon chips we all use. For a few reasons, they've become obsolete. I can tell you that you'll likely hear NO audible quality difference by using them, and it may sound worse than the typical dual op amps that we use.
As for the one you're suggesting, I don't know anything about it. If you take a look at the datasheet and it says it's a dual op amp, it'll work fine. Any dual op amp will work.
