Permanent magnet Alnico is an iron alloy with the addition of aluminum (Al), nickel (Ni), cobalt (Co), and a few other components that enhance magnetism in addition to iron. Alnico alloys have high coactivity and high Curie temperature. Alnico alloys are hard and brittle and cannot be cold worked, so they must be made by casting or sintering.
Alnico magnets are used in electric motors, electric guitar pickups, microphones, sensors, speakers, traveling wave tubes, cow magnets, etc. If you would like to customize alnico magnets or learn more about permanent magnetic materials, please do not hesitate to contact Souwest Magnetech alnico magnets supplier.
According to different production processes, there are Sintered AlNiCo and Cast AlNiCo. Most of the products are round and square in shape. The casting process can be processed and produced into different sizes and shapes; compared with the casting process, the sintered products are limited to small sizes, and the dimensional tolerances of the produced blanks are better than those of the cast products, and the magnetic properties are slightly lower than those of the cast products, but the processability is better. Among the permanent magnet materials, cast Alnico permanent magnets to have the lowest reversible temperature coefficient and can work at temperatures up to 600 degrees Celsius or more. Alnico permanent magnets are widely used in various instrumentation and other applications.
The advantages of Alnico magnets are high reminisce (up to 1.35T) and low-temperature coefficient. At a temperature coefficient of -0.02%/°C, the maximum operating temperature can be around 520°C. The disadvantages are very low coactivity (usually less than 160kA/m) and a non-linear demagnetization curve. Therefore, although Alnico magnets are easily magnetized, they are also easily demagnetized.
Alnico 2: Sweet and Smooth The Alnico 2 magnets are renowned for their sweet and smooth tonal quality. Alnico 2 magnets are perfect for musicians seeking a warm, vintage tone. These Alnico 2 magnets are known for their soft treble and excellent sustain, making them a popular choice for blues and jazz musicians.
Alnico 3: Balanced and Articulate The Alnico 3 magnets are characterized by their balanced and articulate sound. Alnico 3 magnets offer a clear, full-bodied tone, making them ideal for musicians who require a versatile and responsive pickup.
Alnico 4: Bright and Punchy For those seeking a bright and punchy tone, the Alnico 4 magnets are the perfect choice. Alnico 4 magnets deliver a strong mid-range punch and clear high-end sparkle, making them ideal for rock and pop genres.
Alnico 5: Versatile and Dynamic The Alnico 5 magnets are known for their versatility and dynamic range. Alnico 5 magnets offer a balanced tone with enhanced bass and treble frequencies, making them suitable for a wide range of musical styles.
Alnico 8: Powerful and Aggressive Lastly, the Alnico 8 magnets are designed for musicians seeking a powerful and aggressive tone. Alnico 8 magnets deliver high output with a strong magnetic field, making them ideal for heavy rock and metal genres.
