Our ferrite hook magnets have a quality of Y30BH. In addition, they are axially magnetised, i.e. they are magnetised along an axis. These ferrite hook magnets are suitable for applications requiring a temperature of 100°C. If higher temperatures are required, we can manufacture them on request. In terms of weight, our ceramic hook magnets have a weight that varies between 4.3G and 213.84G. This data depends on the measurements you need, as we can manufacture them to measure on request.
