In rare earth neodymium magnets, the grade refers to the materials used in the production process. Material “grades” range from N27 to N52 (higher is stronger).
Some grades may be followed with a letter designation, which denotes a special increased temperature feature of a product.
M – (Max 100°C)
H – (Max 120°C)
SH – (Max 150°C)
Super High temperatures
UH – (Max 180°C)
Ultra High temperature
EH – (Max 200°C)
Extremely High temperature
Generally, price escalates as the product grade rating increases.
Big Cube Zinc Coating Neo Magnet
1. RAW MATERIALS
Minerals – such as Neodymium, Iron and Boron – are sourced from all around the world.
Many required elements, such as Neodymium, are very uncommon and newver found on their own. They must be heavily refined & processed before the material is useable!
2. MILLING & BLENDING
The course materials are jet-milled down into powder, which is then blended into an incredibly precise composition.
At this point the powder is in danger of oxidation, and must be kept in an inert gas, such as Argon!
The mixture is compacted into shape and a magnetic field is appled to ensure all particles are aligned… this maximises magnetic output!
The ingredients are sintered at temperatures in excess of 1,000°c to achieve 99% density.
During this process, the magnet will shrink by nearly a fifth of its size! They are rapidly cooled, then re-heated to 600°c before being cooled again.
A “clean-up” takes place by sanding the magnet into exact measurements. Finishing touches are added last.
Finishing touches may include the addition of a glossy nickel protective coating, re-magnetising, and marking polarity.
