Delta magnets

'High energy' magnets are manufactured using a sintering process of alloy powders. Sintered magnets are very hard and brittle and can only be machined using diamond tools and before magnetization. A preferred orientation is applied to the magnet during manufacture. Magnetization is possible only in this preferential orientation (anisotropy). Magnetic values ​​are not weakened by strong reverse magnetic fields. The maximum operating temperature depends on the dimensioning (L / D ratio). The Delta magnet can be used up to the temperature of liquid helium. Under normal environmental conditions, the Delta magnet can be used without additional surface protection. Samarium-Cobalt magnets can be supplied in different qualities depending on the use case.
