"The metal is one of the most effective hardeners for platinum and
palladium, and is alloyed with these metals to make electrical contacts
for
severe wear resistance."

The extreme hardness of these contacts means that since perfect
flatness
cannot be achieved in relay contacts, such contact is limted to a
discrete
number of points.

Really? How hard is extreme hardness? Ever occur to you the harder the
contact the smoother it can be polished? Which factor takes precedence
in
determining contact resistance, smoothness or malleability?

Failure to answer the questions noted.

Yep, you failed again, sock puppet Morein.
