Even though they are called “rare earth” or “neodymium” magnets, they contain a lot iron and other metals. All of the neodymium, iron, samarium, cobalt, nickel, etc comes from the ground.
Grinding and Mixing the Alloy
Once the raw material is available, it must be ground to a powder and mixed to create the various grades of materials. Different mixtures will create materials with various magnetic properties. Some are stronger, others more durable, and others can last longer in high temperatures.
The next step is to press the mixture together into a form.
Particle Alignment
We use a large electromagnet to optimize the pressed mixture for magnetization.
Once the particles are aligned, we can sinter the material to firmly lock everything in place.
The material can be further refined by cutting and machining to smaller pieces. Tolerances are usually +/- 0.05mm. Micro machining specialists can work with much higher tolerances.
Plating / Coating
After the final shape of the magnet is finished, we must coat or plate each piece to protect from corrosion. This is especially true for Neodymium Iron Boron magnets which are very susceptible to corrosion. Normal platings include Nickel, Nickle + Copper + Nickel, Epoxy Coating, Gold, ABS Plastic, and Zinc.
Magnetization happens after all of the machining and plating. Neodymium magnets can only be magnetized in the direction they were setup for in the alignment phase.
Each magnet is inspected and sampled for quality assurance tests.
