Wirebonding setup is often painful.  Using "setup parts" which weren't made at the same fabricator as the parts you are planning to use is only helpful for training on the machinery.

Gold plated (over nickel of course) Kovar about 0.5mm thick welds (wirebonds) readily and is pretty easy to get.  So I recommend that for training purposes.

If you REALLY want to play with semiconductor die, then I'd recommend calling ChipSupply or one of the other die distributors to see if they care to unload junk parts.  But they could be junk because they have too small a parameter "window" for production wirebonding, so you could just be learning how difficult things can be by getting them.
