Future prospects magnetic trap

NdFeB advantage is the high cost performance, with good mechanical properties, easy cutting; downside is that the low point of the Curie temperature, the temperature characteristics are poor, and easy-powder corrosion, must be taken to the surface by adjusting the chemical composition and treatment methods make it possible to improve, to achieve the requirements of practical application. NdFeB powder metallurgy manufacturing process, will contain a certain proportion of raw materials such as: neodymium, dysprosium, iron, cobalt, niobium, praseodymium, aluminum, boron, iron, medium frequency induction melting furnace smelting by an alloy ingot, then broken into 3 ~ 5μm powder, trap magnets and pressed in a magnetic field molding, sintering the green compact after molding and tempering aging in a vacuum sintering furnace, thus obtaining a permanent magnet has a magnetic blank. After rough grinding, drilling, slicing and other processing steps, and then the surface treatment you need to get the NdFeB products.
Tungsten radiation shield is made of flexible heat shield immersed in radiation shielding device tungsten iron metal powder made of silicone polymer. With damage to the environment, radiation hazards to human gradually strengthened. Thus radiation means has gradually been valued by the people. As a tungsten radiation shielding material began to be widely used.
