Hi,

Is copper wire in 1.5mm to 2.5mm suitable for wiring branch
styles? -
its a lot cheaper than the bronzed aluminium sold for styling,
but
would it corrode on the tree and damage it?

Unless you're a lot more experienced than me (4 yrs), I'd
recommend spending the extra money for the aluminium wire.

Copper has to be annealed and is harder to bend. I've done a lot
more damage to my trees with copper than I ever did with
aluminium.

Wire can be re-used (NB: I'm not advising that you un-wind the
wire from the branch, in fact, don't do this), but there are
times aluminum wire can be recovered and reused without having to
anneal it. Copper *must* be annealed before you can use it
again.

My 2 cents, FWIW.
