Neodymium iron boron magnet

Neodymium iron boron magnet is one of the rare earth permanent magnet materials with outstanding performance. It is an alloy magnet composed of metal neodymium, iron, boron and other trace elements and made by powder metallurgy process. Neodymium iron boron magnet has high remanence, high coercive force and high magnetic energy product, which is cost-effective. And has very good machining performance. So neodymium iron boron magnet is called magneto king.

01. Introduction to neodymium iron boron

Neodymium iron boron magnet is one of the rare earth permanent magnet materials with outstanding performance. It is an alloy magnet composed of metal neodymium, iron, boron and other trace elements and made by powder metallurgy process. Neodymium iron boron magnet has high remanence, high coercive force and high magnetic energy product, which is cost-effective. And has very good machining performance. So neodymium iron boron magnet is called magneto king.
The surface of Nd-Fe-B magnet has poor anti-oxidation and anti-corrosion ability, so the surface needs to be electroplated under normal conditions. Gold neodymium magnet company's electroplating types include phosphating, gold, silver, zinc, nickel copper nickel, epoxy resin and so on.
Neodymium iron boron magnet is the third generation of rare earth permanent magnet. The main component of rare earth metals is abundant in China. The output of rare earth magnets in China accounts for about 70% - 80% of the world's total production.

03. Neodymium iron boron production process

Semi iron smelting and packaging production -- rolling mill processing -- rolling mill -- rolling mill processing -- Inspection -- after-sales service.

04. Introduction of neodymium iron boron coating

remarks:
The effect of fog is different due to different plating processes (fog salt test results of small products are hung for a long time).
1. Salt test (SST) condition: 5% chlorine 3, pressure test (PCT) condition: at 2 atmospheres
Check the adhesion of the coating at 95% relative humidity and 121 ℃
4. The coating quality test includes falling heat test, cold test, constant humidity test and constant humidity test.
