KOERZIMAT 1.097 MS

Systems for measuring the saturation polarization σs and Js

Reliably determine saturation polarization. The KOERZIMAT 1.097 MS is a measuring system for the fast and precise determination of mass-specific saturation polarization σs and volume-specific saturation polarization Js. Measurement is performed according to IEC 60404-14 using the pull-off method in an open magnetic circuit and is largely independent of sample geometry. This allows even complex-shaped samples to be tested without requiring a predefined geometry.

The measuring system uses a powerful permanent magnet in a Halbach arrangement to saturate the sample. As the sample is withdrawn from the homogeneous magnetic field, its magnetic dipole moment is measured using a pair of Helmholtz coils and a fluxmeter. The sample mass is additionally taken into account to calculate σs, while the sample volume or density is required to determine Js.

Typical applications include quality control of hard metals according to ASTM B886, monitoring the degree of sintering and carbon balance, and determining the amount of tungsten dissolved in cobalt as well as the free iron, cobalt or nickel content in powders and hard metals. The system is also suitable for characterizing soft magnetic components, investigating new alloys and determining magnetic phases in steel alloys.

With the MS 26 × 60 for particularly small samples and the MS 31 × 69 for larger sample masses, two system variants are available for different testing requirements.
