You need to buy small magnets with holes. Welcome to the Courage Magnet Factory in China. We can customize small magnets with through holes (straight holes) or countersunk holes for you. You can choose NdFeB or other weak materials. The magnetic performance is generally above 3000 Gauss. If you need to know its price, please send us an inquiry, thank you!
Ndfeb magnet use note:
1. The surface of Ndfeb magnet is protected by electroplating and has the effect of rust prevention and corrosion resistance, but if it is not used in time, please store it in a dry environment.
2, Ndfeb strong magnetic magnetism is very strong, so please stay away from your related electronic products, such as magnetic card, computer, mobile phone and so on.
3. Ndfeb strong magnetic material is hard, brittle and strong magnetic field. It should be handled lightly (especially large size and thin sheet).
4, when the magnets are not separated from each other, it is recommended to push staggered, must not be hard breaking pry.
5, NdFeb strong magnetic units are mm, so you should see the size when you buy, you can also choose to draw the first sample quotation and order bulk goods.
6, the magnet is divided into different series of brands, there are different high temperature resistance limits, and courage magnet manufacturers can also customize high temperature resistance magnet.
