Hello all.

Certainly interesting in that the temperature and electrical resistance are
opposites! I was looking for such a substance awhile ago.

It Sounds pretty deadly to breath in its powered form though. How much is in
unknown insulators???

Beryllium copper makes an excellent conductive spring!

Hi Godfrey,  all,
    I would not be terribly concerned about those insulators, but as
Gerry says,  don't do anything to make dust....if you need to saw or
file them(can't imagine why you would), do it under water or at least
with water running over them.  It wouldn't hurt to wear latex gloves
too.   Here's a link that makes it sound pretty scary....I sure would
not breathe the dust.   Mike

Hi Godfrey,

I suspect there is no problem as long as it remains in ceramic
form.  Just dont powderize it and breathe it in.
Dont know what the insulating properties are of beryllium oxide.
