When understanding the actual measurement of 1mm, one can see it as the thickness of three business cards stacked together. When observing a magnet, 1mm is the common requirement as if it is less than, the magnet starts to lose the strength needed for the required pull force.
All magnets begin their process through powder metallurgy. In this process, composition is pulverized into fine powder, compacted and heated to cause densification via sintering.
Presently, most of the ultra-thin magnets required by customers in the market are NdFeB strong magnets, such as D5*1, D10*1, D15*1. Thus, reducing the width is not recommended as they are easily broken during adsorption.
How thin can your company customize the magnet?
Currently, the thinnest sintered NdFeB magnet squares produced by our company can reach 0.4mm for special applications.
Option:
Ferrite magnets.
Although it does not contain the same adhesive force as NdFeB magnets, depending on practical usage it is suitable for high frequency, low power and weak electric field surface thus popular for everyday applications. While affordable, it provides good endurance, very resistant to being demagnetized and high magnetic permeability. Ferrite magnets thickness can be as thin as 0.65mm.
