Does anybody know a good copper to aluminum epoxy

I work in a refrigeration laboratory. We are not having luck soldering male copper tubes into aluminum swaged tubes. We need to find an epoxy that we can apply to both tubes then put them together. The joints are pretty tight fitting. They also need to hold pressures of up to 200 PSI. It doesn't have to be a permanent fit though. It would only have to last long enough for us to test an aluminum refrigeration coil. Could you possibly help me with this problem?

To join dissimilar materials we use a very strong adhesive that is manufactured by a company called LORD CORPORATION....They are engineered adhesives for industrial use and there should be a product that will work well for your application. This stuff is as tough as steel after 24hrs.

Good Luck,
