FAQ - Frequently Asked Questions
What are neodymium, ferrite and AlNiCo magnets made of?
In our web shop we sell permanent NdFeB, ferrite and AlNiCo magnets in various sizes and shapes. All types of magnets stand out due to different features.

Neodymium iron boron (NdFeB)
Neodymium is the strongest known material for permanent magnets.
Our super strong magnets are made of a composition of neodymium, iron and boron (NdFeB). The exact chemical formula is Nd2Fe14B. Neodymium magnets differentiate themselves from conventional ferrite magnets through a much higher remanence and coercive field strength.
Ferrite magnets are commonly known as "refrigerator magnets". They are the most used permanent magnets worldwide, because they are very cheap to produce and heat and corrosion resistant. They are uncoated and are dark grey in colour.
We carry affordable ferrite magnets in disc, block and ring shape.
Generally, you differentiate between two material mixtures for ferrite magnets, but we only carry the non-hazardous strontium ferrite.

Aluminium nickel cobalt (AlNiCo)
We sell AlNiCo magnets (chemical formula AlNiCo5) exclusively for school experiments. AlNiCo has only a low adhesive force and loses its magnetisation relatively easily. But you can shape this material into fancy shapes, like horseshoe magnets.
