Alnico magnets

Alnico magnets, made from an alloy of aluminum, nickel, and cobalt (AlNiCo), are ideal for manufacturing magnets with complex shapes. Additionally, this type of magnet has good heat resistance and is mechanically very strong. Casting is the most commonly used production process for these magnets.

For example, AlNiCo magnets are used in ABS braking systems in cars, sensors, guitar components, medical devices, alternators, and other applications.

Advantages of Alnico Magnets:
– Highly resistant to corrosion
– Excellent thermal performance
– Quality and reliability

Applications of Alnico Magnets:

What should you consider when using Alnico magnets?

AlNiCo is a heat-resistant magnetic alloy. The processing of Alnico magnets requires special attention. This alloy can be easily demagnetized.

Alnico magnets have several important characteristics:

– Low coercivity
– High residual induction value, which in certain shapes can produce very strong magnetic fields
– Maximum operating temperature of up to 450°C
– Complex shapes are possible through casting, but large casting cavities can affect the magnetic field
– Contains relatively expensive raw materials like nickel and cobalt

Processing and Production of Alnico Magnets:

Casting, pressing, and sintering are production methods for AlNiCo magnets.

Casting Alnico magnets involves low molding costs due to the use of sand molds. Post-processing is not necessary. However, casting pores lead to an unattractive finish, and large casting cavities can affect the magnetic field.

Pressing and sintering ensure Alnico magnets with better mechanical properties, though with lower magnetic performance.

To avoid demagnetization, the correct length-to-diameter ratio is important.

AlNiCo has excellent corrosion resistance, so surface treatments are not required. However, if your application requires coating for hygienic or cosmetic reasons, these magnets are easy to coat.

Alnico magnets are brittle and can only be processed with special machining techniques, such as grinding, cutting, and EDM, resulting in magnets with precise tolerances.

What are the specific properties of Alnico magnets?

AlNiCo is a highly heat-resistant magnetic alloy. In addition to this property, Alnico magnets are chemically inert and corrosion-resistant.

AlNiCo is an alloy composed of the following metals in addition to iron:
– Aluminum (Al)
– Nickel (Ni)
– Cobalt (Co)
The material also contains copper and sometimes titanium.
