How to choose an alnico magnet

When choosing an Alnico magnet, consider the grade, coating or construction requirements, and operating temperature of your application.

Grade

Our current Alnico range includes Alnico 5. Check the grade and specifications listed on the individual product page, particularly where magnetic performance is important to your application.

Coating

Coating requirements depend on the product construction and the environment in which the magnet will be used. Check the individual product specifications where exposure to moisture, corrosion or other environmental conditions is a consideration.

Temperature

Alnico magnets are valued for their temperature stability and can be well suited to applications where elevated temperatures are a factor. Suitability still depends on the specific magnet and operating conditions, so contact us if temperature is a key requirement.

FREQUENTLY ASKED QUESTIONS

Can Alnico magnets be demagnetized?

Yes. Alnico magnets are permanent magnets, but they can be demagnetized by strong opposing magnetic fields or unsuitable magnetic conditions.

They are more susceptible to demagnetization than some other permanent magnet materials, so correct handling and application design are important.

Do you ship alnico magnets outside Canada?

Yes. We ship our Alnico magnets worldwide. Shipping costs depend on your order weight, selected service and destination, with estimated shipping costs available before you place your order.

Can Jobmaster help with custom alnico sizes or assemblies?

Yes. We can help with custom magnet requirements where a stock Alnico magnet doesn’t meet your application. Contact us with details such as the dimensions, intended use and operating environment, and we can discuss the options available.

What should I do if temperature is an important part of my application?

Alnico magnets are valued for their temperature stability and can be a good choice for applications involving elevated temperatures. Suitability depends on the specific magnet and operating conditions, so contact us with details about your application, and we can help you determine the appropriate option.
