Sure you can do this, but get a few of these, as the odds of getting it
right the 1st time is slim.

As used in thermal switches. Instead of in form of a bimetal strip and
continuous curving with temperature, these are 0.5 inch diameter and
make a
definite flip from concave to convex at a specific temperature. About
1mm of
abrupt movement gives a very positive transition for the switch
contacts.
Would it be possible to change the characteristic temperature by
grinding
back a spot/ring/radii? on one face? which face? or would it just
destroy
the action/activation force?
According to patent
"Laser adjusted set-point of bimetallic thermal disc"
it is done at production , for precise adjustment, but no specific details
of patterns/which surface/degree of variation. I'm more interested in
adjusting otherwise useless batch made for set point of 16 degree C up to
50 or 60 degree C, with no great precision, +/- 10 deg C would be fine
