Thanks Zfennel for the link,
Correct me if i am wrong, corecell is slightly better as far as compression. Does H80 have any advantages over Corecell?

you'll find the real difference between the two is allowable strain.
the divinycell is more brittle and likely to fail due to poor flexure resistance and not excessive load.

the main advantage of divinycell is availability.

Zfennel is right about the strain, but the newer Divinycell is tougher than it used to be (i.e. not as brittle). Divinycell has better compression strength and stiffness which makes it better at resisting denting and resulting skin failures if you use a thin covering of fiberglass. It's also a bit lighter than Corecell. Each core has its advantages, but they'll both make good boards.

What kind of board are you planning on making?

I'd actually use Corecell T500 as it's a bit cheeper and you can stick it in your oven to post cure your board if your using epoxy (A500 doesn't like being post cured at high temperatures). In the end of the day T400 would probably work as well depends on your laminate.

Cheers
Chris

See above post about core comparisons.

Happy board building
