System for the measurement of coercivity HCJ, hysteresis J(H) and relative permeability µr(H)
Material evaluation based on magnetic properties. Magnetic values such as coercivity HCJ correlate with numerous important process parameters and material properties in the production of sintered hard metals and powder-metallurgical components. The KOERZIMAT 1.097 HCJ measuring system by FOERSTER facilitates the accurate, automatic, and fast measurement of the coercivity HCJ. The largely geometry-free measurement is particularly suitable for testing samples with complex shapes. The extension module J-H measurement offers the possibility to determine the complete J-H Hysteresis on soft magnetic steel incl. the initial curve.
The applications of the KOERZIMAT include the control of the sintering level and particle size of hard metals and the quality control of metallic powders for the production of magnets and hard metals. The unit can also be used for monitoring the quality of the annealing and the mechanical stress state of soft-magnetic components (SMC) and for controlling electromechanical components in the electronics, automotive, computer, and clock sectors.
