KOERZIMAT 1.097 HCJ/J-H

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.

Application notes

Measurement of coercive field strength in the development of special magnetically soft alloys

Small deviations in coercivity can reduce efficiency and increase losses. KOERZIMAT measures HcJ precisely, regardless of specimen geometry.

Incoming Material Inspection for Reed Switch Production

Coercivity deviations can impair reed switch performance. KOERZIMAT precisely verifies incoming material to ensure reliable switching behavior.

Production Process Monitoring for Components of Electromagnetic Actuators

Forming processes can change the magnetic properties of soft magnetic materials. KOERZIMAT reliably monitors coercivity throughout production.

Assessment of Carbide Grain Size on Small Hard Metal Specimens

Incorrect carbide grain sizes in hard metal specimens can reduce tool life and performance. Coercivity measurement quickly and reliably determines the grain size.
