Magnetic technology co. , LTD. Engineer tell you whether or not the ndfeb strong magnet or general magnet poles are all constant, but people can use technology to put the same magnet filling out many a pole, pole, of course, must be fully coupled, in other words, a piece of magnet can have multiple N pole and a corresponding S pole.
Magnet magnetic is influenced by the external environment and weak, such as the Curie temperature, magnetic field, or else the interference of electromagnetic field, etc.
To varying degrees of different material of the magnet, fade.
To make magnetic magnet with magnetic again, recede the magnetization is only applied magnet magnetization way again.
Metal magnet, that is, it is often said of ndfeb strong magnet, ferrite magnet magnetic is stronger than ordinary, because the surface of the metal magnet with magnetic field strength is greater.
It is determined the physical properties of different magnetic materials.
Ndfeb magnet surface treatment can be divided into: galvanized epoxy gold-plated nickel plated black zinc plated, whatever the electroplating, plating technical personnel must know the characteristics of ndfeb ndfeb magnet.
Ndfeb magnet powder metallurgy class, surface activity is relatively large, be especially careful when in phosphating, not hurt ndfeb magnet surface characteristic, surface of the product or plating out will not level off is smooth, metal plating and electroplating magnets on distribution law is different, but the plating processes and facilities are the same.
The magnet factory should note when selecting plating supplies to discuss.
Before plating fillet to do reasonable Angle, the Angle of the small not easy to plating, big Angle can cause the size of the product is too small, not accepted by the customer.
Moderation of electroplating step, voltage regulating the temperature of the bath water must be appropriate, any one element was not well done, can make out the effect of electroplating can not meet the standard, the requirement of the salt spray test pass it.
