Is this intercool made of copper? How do I clean it

[Mikeysthings]

Rebuilding engine after SC failure. Metal pieces in intercooler along with oil.

I was wondering would be good to clean it with? Also is this made of copper?

I'd probably use solvent, but if you don't have a solvent tank, using another degreaser such as carb cleaner should do the trick. Then just blow it out with compressed air.
