AlNiCo magnets

Aluminium-nickel-cobalt (AlNiCo) magnets are perfect for magnets with complex shapes.

In addition, this magnet type has good heat resistance and is mechanically very strong. Casting is the most widely used production process for these magnets.

For example, AlNiCo magnets are used in: ABS braking systems in cars, reed contacts, sensors, guitar parts, medical devices, alternators.

  • Highly resistant to corrosion
  • Excellent thermal performance
  • Quality and reliability
  • Multiple moulds

What should you take into account when using this magnet type?

AlNiCo is a highly heat resistant magnetic alloy. Processing AlNiCo magnets requires special attention. This alloy has the ability to easily demagnetize.

 

AlNiCo has a number of important characteristics:

  • low coercivity
  • high residual induction value, in certain forms, these cause very powerful magnetic fields
  • maximum operating temperature of up to 450 °C
  • complex shapes are possible through casting, but large casting cavities influence the magnetic field
  • casting pores
  • contains the relatively expensive raw materials nickel and cobalt

What you need to know about AlNiCo manufacturing and processing.

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

 

Casting AlNiCo magnets involves low moulding costs due to the application of sand moulds. Post-processing is not, or hardly, required. However, casting pores lead to a less attractive whole. And large casting cavities can affect the magnetic field.

 

Pressing and sintering ensure magnets with better mechanical properties versus lower magnetic performance.

 

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

 

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

 

AlNiCo magnets are fragile and can only be processed with special machining techniques. With grinding, cutting and EDM techniques we produce magnets with precise tolerances.

How do we ensure manufacturability, reliable quality and stable supply?

The magnetic properties of each magnetic alloy are different. Many manufacturers deliver a quality that does not meet the requirements you set.

Over half a century, we have built up a strong network of controlled and certified manufacturers. In addition, we are IATF and AS9120 certified. We assess in advance whether your magnet can be made and whether the desired properties are measurable.

 

In addition to manufacturability, reliability and quality, it is also important that you receive a magnet with a stable price and delivery time.

 

Magnets that:

  • meet the right magnetic specifications
  • are high-quality and reliable
  • are certified and inspected.

 

As there is a lot of variation in ferrous magnets, our team is happy to help you make the right choice. Send us your inquiry about AlNiCo magnets: info@goudsmitmagnets.com.

What are specific properties of AlNiCo Magnets?

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

 

AlNiCo is an alloy; the following metals are added to iron:

  • aluminium (Al)
  • nickel (Ni)
  • cobalt (Co)

The material also contains copper and sometimes titanium.
