Once the particles are aligned, we can sinter the material to firmly lock everything in place.
Milling and Cutting
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.

Neodymium Iron Boron magnets were commercially introduced in the early 1980s. They are widely used today in many different applications. The cost of this magnet material (on a dollars per energy product basis) is comparable to that of Ferrite magnets. On a dollars per pound basis, the cost of Neo magnets is about 10 to 20 times that of Ferrite magnets.
Note that NdFeB magnets are covered by various patents (held by Neomax) and only licensed materials are allowed into the USA. There are a number of sources that do sell unlicensed products to those willing to purchase them. HSMAG does not sell unlicensed materials.
Super Neodymium Magnets Block  Key Benefits
Very high strength
Relatively low cost (by weight about 20 times Ferrite magnets, by “Dollars per BHmax” about 1.5 times Ferrite magnets).
Relatively easy to machine, compared to Alnico and SmCo magnets.
