Hangzhou Xinfeng Magnetic Material Co., Ltd. specializes in the supply of permanent magnetic materials, the main are Neodymium and Samarium Cobalt. Rare earth permanent magnetic material is a new high-performance permanent magnet materials developed in recent decades, compared with the traditional permanent magnetic materials, its comprehensive magnetic properties are several times higher to dozens of times. Samarium cobalt permanent magnetic materials has high Curie temperature, low temperature coefficient and stable chemical properties, which is especially suitable for motor, instrument and other applications.
Samarium cobalt alloy is an important magnetic material, which has a large application market and deep research value. The composition of cobalt in samarium cobalt alloy accounts for about 50%, so it has certain recovery value for cobalt in waste materials. If the pure samarium cobalt alloy material is dissolved in hydrochloric acid and nitric acid, there is basically no acid insoluble substance. If it is magnetic samarium cobalt waste, there will be different degrees of oil mixed with impurity elements that are difficult to dissolve. To ensure that all cobalt is transferred to the solution without loss, the insoluble material is treated by alkali fusion and the cobalt content is determined by plasma spectroscopy.
