Will permanent magnets rust when exposed to water? Permanent magnets rust? Yes! Although permanent magnets have strong magnetic properties, they are not “invulnerable”. Especially the common NdFeB magnets, whose main component is iron, are easily oxidized and rusted in a humid environment. Why do permanent magnets rust? Material composition: The main component of most permanent […]

The difference between FeCrCo and AlNiCo magnets FeCrCo (iron-chromium-cobalt) and AlNiCo (aluminum-nickel-cobalt) magnets are two distinct types of permanent magnets, each with unique properties and applications. Here are the main differences: Composition: FeCrCo magnets : Primarily made of iron, chromium, and cobalt, with possible additions of other elements like nickel or copper to enhance specific […]

What is Electropermanent magnet？ An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by pulses of current in a winding of wire around the magnet portion. The magnet consists of two parts, one of a “hard” (high coercivity) magnetic material and […]

Main production process 1.Milling: The process begins by grinding the raw materials (aluminum, nickel, cobalt, etc.) into a fine powder. 2.Pressing: The powdered mixture is then pressed under high pressure in a mold shaped like the desired magnet. 3.Sintering: Next, the pressed material is heated in a hydrogen furnace at a very high temperature. This […]

Magnets can be classified into two main categories based on their magnetic properties: isotropic and anisotropic. Isotropic Magnets Isotropic magnets have a random direction of magnetization throughout the material. This means that the tiny magnetic domains within the magnet are not aligned in any particular direction. Because of the random orientation, isotropic magnets tend to […]

AlNiCo (Aluminum-Nickel-Cobalt) magnets can be classified based on their orientation into fully oriented, semi-oriented, and non-oriented types. Here’s an overview of each: 1.Fully Oriented AlNiCo Magnets: These magnets are produced by heating the alloy above its Curie temperature in the presence of a strong magnetic field. The resulting magnets have a […]

Magnetic therapy is a type of alternative medicine that uses magnets to relieve pain. It is a popular treatment for a variety of conditions, including arthritis, headaches, and back pain. How Magnetic Therapy Works The theory behind magnetic therapy is that magnets improve blood circulation and reduce inflammation. This, in turn, is thought to help […]

What is Magnetic Drum Separator？ A magnetic drum separator is a type of magnetic separator used to separate tramp iron or ferromagnetic materials from bulk materials on a conveyor belt or vibrating feeder. The magnetic drum separator consists of a stationary magnetic element, placed inside a rotating stainless-steel drum. The drum rotates at a predetermined […]
