neodymium magnet coating

Why need Coating & Plating?

Neodymium magnet coating is one of the main factors in production. Because the materials of neodymium magnets are unstable since they contain a lot of iron. They can have negative chemical reactions – corrosion (rust) – under hot and humid working conditions. This will weaken the magnetic performance and even shorten their life spans. And the coating can prevent or slow down oxidation very well. magnet coating

What should be considered when choosing a coating

In many cases, people just consider how to make sure the neodymium magnet will not rust. But in some high technology cases or medical cases, there are many factors should be conisder, likes:

How many kinds of magnet coating?

There are many standards for distinguishing coatings, and Osenc mainly divided into two types:

One layer coating

Nickel (Ni) Rubber Epoxy Zinc (Zn) Gold (Au) Tin (Sn) Titanium (Ti) Titanium Nitride (TiN) Parylene C Everlube Chrome PTFE(Polytetrafluoroethylene) Phosphate passivation

multi-layer

Nickel-Copper-Nickel Nickel-Copper-Nickel, plus Rubber Zinc, plus Rubber Nickel-Copper-Nickel, plus Parylene Nickel-Copper-Nickel, plus PTFE Tin, plus Parylene Zinc chromate

Adhesive

Even with the same adhesive, different magnet coating will stick differently. Please choose the right plating according to your needs.
