A hysteresis alloy’s composition, orientation and heat treat are optimized to produce maximum hysteresis losses. Generally materials are engineered to reduce losses. Hysterloy is usually supplied in the form of rings with a composition close to that of Alnico 5. The rings are oriented circumferentially during a heat treat cycle that is optimized for maximum losses.
