This document provides information about the composition, magnetic characteristics, thermal characteristics, and mechanical properties of N35 neodymium iron boron magnets. The magnets are produced via powder metallurgy, have a residual induction between 1.18-1.23 T, a coercive force between 868-955 kA/m, and maximum energy product between 263-287 kJ/m3. They have an operating temperature of 80°C, a Curie temperature of 310°C, and reversible temperature coefficients for residual induction and coercive force. The preferred geometry for these magnets is a ring.
