A table on the Materials Preservation web site provides data on the
corrosiveness of seven woods towards various metals. See
<URL:> This metal attack will
be mainly due to acidic volatiles so the effects on cellulosic
materials should be in the same order, which is

    oak=beech > chestnut > birch > fir > walnut=elm.

The latter two woods produced no metal corrosion under the
conditions tested.
