The difference between the strong magnet and ordinary magnet _ ndfeb strong magnet manufacturers

Strong magnet or ordinary magnet polarity is constant, but you can use the same magnetic pole to fill many, even if there is a N pole and S pole pole accordingly. The influence of the external environment, such as temperature, other interference magnetic field or electric field, etc. , will weaken the magnetic. Different material of magnet, its resolution is different. In order to make the rotten magnet magnetized again, can only make the magnet magnetization magnetization. Metal magnets, we call it a strong magnet, stronger than ordinary ferrite, because the surface of the metal magnet magnetic field stronger after magnetization. This is decided by the physical properties of different magnetic materials. Strong magnet surface treatment can be divided into galvanized, nickel, zinc, gold, black, epoxy to wait for a few kinds, whatever the electroplating, plating engineer should know the Nd - Fe- B) the characteristics of strong magnet. Strong magnets belongs to powder metallurgy, high surface activity. Phosphating, should pay special attention not to damage on the surface properties of strong magnets. Otherwise, the surface of plated products will not be smooth. Hardware and electroplating electroplating magnets related formula is different, but the same plating processes and equipment. The choice of electroplating factory should pay special attention to magnet power supply. The chamfer Angle before plating should be reasonable, the Angle is too small not easy electroplating, large Angle will lead to product size is too small, not accepted by the customer. Electroplating process, voltage adjustment should be reasonable, water bath temperature should be moderate, any link has not been well, plating effect is not in conformity with the requirements, the salt spray test can not meet the requirements.
