Strong magnets are now used in a wide range of applications in almost every industry. There are electronic industry, aviation industry, medical industry and so on.
So how to judge the good and bad of NdFeB magnets when buying NdFeB strong magnets? This is a problem that many newcomers often encounter, what kind of magnet is good?
Today, we’ll will teach you some tips to buy NdFeB magnets.
1. first of all, you have to know how the working environment of the magnet you want to use is?
2. there is also how the external environment is so that you can choose the plating needed for the magnet.
3. the requirements of the magnet's magnetic force, temperature requirements?
4. the consistent stability of the magnetic force, the source of raw materials?
The choice of magnetic force can be based on the size of your specifications to choose the material grade, the temperature is specific, below 80 degrees, choose N series, above 80 there are H series, resistant to 120 degrees; SH series, resistant to 150 degrees; UH series, resistant to 180 degrees; and 200 degrees above the EH and AH.
The common plating methods are nickel plating and zinc plating, gold plating and silver plating, etc., which can be produced according to the customer's requirements. If you have high requirements, you can plating epoxy.
Usually, NdFeB is evaluated from two aspects.
1、Appearance
2、Performance
Appearance: whether there are missing edges and corners, whether the plating layer is intact, whether the size meets the design requirements.
Performance: There is a unified standard for NdFeB performance, the main indexes are magnetic energy product, coercivity, remanence, etc.
If you know the above points, you can pick the NdFeB magnet that meets your requirements.
