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 […]

The difference between cast AlNiCo and sintered AlNiCo magnet Cast AlNiCo and sintered AlNiCo are both AlNiCo magnets, but they are different from each other, especially in production process, characteristics and application. Manufacturing Process: Cast AlNiCo magnet: This type is made by pouring a molten alloy into a mold and then allowing it to cool and […]

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 […]

Motorcycle speedometer magnets originated in the 1970s. At first, Alnico2 D23*D13.5*3 was widely used. Later, with the development of the times, Alnico3 D23*D6*4 gradually replaced Alnico2 in order to save costs. They are both isotropic magnets. Speedometer magnets are usually not magnetized. They are magnetized after being installed in the movement and assembled to prevent […]

Here’s how to identify the Alnico magnets mentioned above: Visual clues: Luster: Alnico magnets usually have a metallic luster, while ferrites (ceramics) are usually dark gray and lack luster. Neodymium (NdFeB) magnets can also have a shiny appearance, but it may be a brighter silver or gray. Samarium cobalt magnets usually have a dark gray […]
