Tungsten carbide cobalt magnetism, also known as the saturation magnetization strength of the alloy, is actually the saturation magnetization strength of the magnetic material cobalt. The cobalt magnetism of tungsten carbide is also based on the ratio of its magnetic material cobalt content to that of the alloy, generally the cobalt magnetism is within a certain range, too high and too low, too high will appear carburization, and vice versa, decarburization, both of which are failures for the production of the alloy, HC is the coercive magnetism, which indicates the ability of the alloy to resist the remanent magnetism, that is, the reverse magnetic field strength of the remanent magnetism, the unit is KA/M. Magnetic force and cobalt magnetism have an inverse relationship, generally the higher the cobalt magnetism, the lower the magnetic force
The cobalt magnetism is measured when the sample under test is fully magnetized to saturation in a uniform magnetic field composed of strong permanent magnetic material, and then the specimen is quickly withdrawn from the magnetic gap of the magnetic induction signal detection coil, at which time the magnitude of the magnetic induction signal is input into the microcomputer together with the mass of the sample under test for data processing, and then the desired value of the magnetic parameter is displayed. The cobalt magnetism of the hard alloy is the percentage content of the alloy that produces magnetic cobalt.
