Manufacturing process of sintered AlNiCo

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

Manufacturing Process: Cast AlNiCo: This type is made by pouring a molten alloy into a mold and then allowing it to cool and solidify. This process results in a material with good magnetic properties and shape versatility. Sintered AlNiCo: Sintering involves compacting fine AlNiCo powder in a mold under high pressure and then heating it […]

The difference between fully oriented, semi-oriented and non-oriented AlNiCo magnets

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 […]

Alnico Odometer Magnet and Speedometer Magnet

Odometer Magnet

An Alnico odometer magnet and speedometer magnet are both types of permanent magnets used in vehicles. They are typically made from an alloy of aluminum, nickel, and cobalt (AlNiCo), which gives them several advantages for this application.Usually use Alnico 2 magnet and Alnico 3 magnet. AlNiCo odometer magnets are a reliable and cost-effective choice for […]

How Guitar Pickups Magnet Size Shapes Your Tone

guitar pickups magnet

Guitar pickups are the core component of electric guitar sound. Its tone depends on many factors,of which guitar pickup magnets size is an important one. The size of the magnet will affect the magnetic field strength of the pickup, thereby affecting the tone of the pickup. The main sizes of Guitar pickup magnets used in […]

How to identify Alnico magnets?

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 […]

What is difference between Samarium cobalt and Alnico magnet

Common ground: Both belong to high temperature-resistant permanent magnets. Among them, the working temperature of Alnico magnet can reach up to 550℃, the maximum working temperature of samarium cobalt 1:5 type is 250℃, and the maximum working temperature of samarium cobalt 2:17 is 350℃; Both do not require surface treatment (except for use in special […]

The principle of Geophone magnet

A geophone is a highly sensitive ground motion transducer that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured voltage from the baseline is called the seismic response and is analyzed for the structure of the earth, which has been used by seismologists and geophysicists […]
