Rubber magnet contains a lot of neodymium and iron and other metal substances, easy to rust, so the rubber magnet surface coating is necessary, the surface chemical passivation is one of the good solutions.

Rubber magnetic passivator suitable for rubber magnetic material, cast iron and powder metallurgy and other materials directly passivated surface is a light yellow transparent liquid, specifically for the magnetic rubber magnetic material developed a new type of high efficiency Environmentally friendly passivator indicators comply with the RoHS directive, the agent has a special buffer system, to overcome the corrosion of the workpiece surface and internal, passivation and stable performance.

Rubber magnetic permanent magnet material is based on the intermetallic compound RE2FE14B permanent magnet material. Rubber magnet has a very high magnetic energy product and force, while the advantages of high energy density rubber magnetic permanent magnet materials in modern industrial and electronic technology has been widely used, so that instrumentation, electro-acoustic motor, magnetic separation and other equipment magnetization It is possible to miniaturize, reduce weight and make it thinner.

The advantages of rubber magnetic is cost-effective, with good mechanical properties; lack of Curie temperature is low, poor temperature characteristics, and easy to powder corrosion, it must be adjusted by chemical composition and surface treatment to be improved, In order to achieve the practical application requirements.

Sintered rubber magnetic permanent magnet material is used in powder metallurgy process, the alloy after melting made of powder and pressed into a magnetic field in the pressure of embryos, lamination in an inert gas or vacuum sintering to achieve densification, in order to improve the coercivity of the magnet, Usually require aging heat treatment.
