Mar 16, 2005· It is somewhat related to strength. Very strong materials will have low toughness, i.e. low tolerance for flaws or defects, i.e. incipient cracks. Toughness relates to the amount of energy absorbed in order to propagate a crack. Materials with high toughness require greater energy (by virtue of force or stress) to maintain crack propagation.

Yes. Neodymium magnets are sensitive to heat. Depending on the grade of the magnet, the heat will demagnetize the magnet. We can produce custom magnets that withstand high temperatures. Most of our magnets are grade N40 so if they are heated above 80˚C or 176˚F they will demagnetize and lose their strength. See Magnet Grades for more details. 6.
