People familiar with magnet materials must have heard of Al-Ni-Co magnets. Alnico permanent magnet material is an alloy composed of metal aluminum, nickel, cobalt, iron and other trace metal elements. Al-Ni-Copermanent magnet material is the earliest widely used permanent magnet material, and its preparation process and technology are quite mature. Before the discovery of rare earth perm...
If you've ever purchased a NdFeB magnet, you surely know that almost all NdFeB magnets have a coating, so why don't ferrite magnets need a coating? First of all, let us know about ferrite magnets, which are non- metallic magnetic materials, also known as magnetic ceramics, so there is basically no corrosion problem. It can be seen everywhere in life. For example, the speaker magnet in the radio is...
Magnetic materials are now mainly divided into two categories, one is soft magnetic materials, the other is hard magnetic materials (permanent magnetic materials). Soft magnetic material: high permeability, easy to be magnetized and easy to demagnetize. In the saturation state, the magnetic flux is large, the coercivity (Hc) is small, the total area of the hysteresis loop is narrow and long, and t...
Will the magnetism of the magnetic wheel decrease after long-term use? In the field of automation equipment and industrial transmission,magnetic wheels are widely used for their frictionless, quiet, and low-maintenance performance. But many engineers and buyers share the same concern: Will the magnetism of the magnetic wheel decrease after long-term use? In this article, we explain the truth about...
How to Increase Magnetic Pull Force Without Increasing Magnet Size? Introduction In many industrial, automotive, and consumer electronics applications, magnetic pull force is a critical factor—but increasing magnet size to boost strength is often not an option. Whether you’re designing a compact wearable device, a space-constrained industrial component, or a sleek consumer product, bulky magnets c...
