A treasure of a family "summary" anti-corrosion have tips!
Sintered ndfeb alloy containing active rare earth elements, easy oxidation, easy to rust. In the application, unless the sintered ndfeb is encapsulated, from air and water, or need to do surface corrosion resistance of sintered ndfeb. Common anticorrosive coating has a nickel electroplating, electric galvanized and electrophoresis epoxy resin. Surface phosphating treatment can be a short period of time in a relatively dry environment of sintered ndfeb rust protection.
Sintered ndfeb permanent magnet materials have excellent magnetic, widely used in electronics, electricity, machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields, is one of the more common permanent magnet motor, speaker, magnetic separator, computer disk drives, magnetic resonance imaging equipment instrument, etc 。
