Magnetic properties of cemented carbide:
Cemented carbide is a composite material composed of tungsten carbide (WC) and cobalt (CO). The addition of cobalt gives the final alloy both an excellent hardness degree and good toughness. The percentage of cobalt by weight in an alloy usually ranges from 3 to 30%.
Magnetic properties of cemented carbide are measured as metallurgical the process provides useful information: the magnetic moment provides direct information on the amount of unalloyed cobalt in the non-magnetic phase. So we have DX-9700HC, and now the quality of metallurgical bonding and the eventual appearance of undesired phases can be assessed. Coercivity HCJ data provide an indication of grain size: the higher the HCJ reading, the finer the grain size.
The measurement coil has an embedded sensor and a slot to insert a Hall probe, and the sample is placed in the sample jig and placed into the measuring coil. The fixture size will be customized according to the customer measurement sample size.
Instrument Software
Our proprietary 9700SW software automatically manages the DX-9700HC magnetometer measurements, including the comparison of different curves and statistical analysis. The software ensures that the measurement process is precise and absolute, guiding the operator to correctly set the sample parameters.
The automated assistant notifies the operator and makes recommendations for appropriate steps or settings.
The software also provides automatic creation of printed reports, a database search feature and curve comparison.
