Magnets need to be coated or they will corrode quickly when left exposed to the elements.
All magnets, except for weld clamp magnets, magnetic sweepers, hand magnets, and magnetic mounting pads can be coated in a large range of different materials. The most common coatings are listed below:
Nickel-copper-nickel Customized Segment Magnet
Nickel-copper-nickel coatings, (known as nickel coatings), consist of three different coats: nickel, a layer of copper, and then a second layer of nickel.
This type of coating can be painted over, which makes a nickel-copper-nickel coating more visually attractive than the other magnetic coatings available.
This method of painting the coating is used on bar magnets which need the different magnetic poles to be painted in different colours for educational purposes.
Epoxy is a type of plastic coating that improves the corrosion resistance of a magnet. This type of coating will last a long time if it is not damaged in any way, however it is easily scratched which makes it one of the least durable coatings for a magnet.
Magnetic discs, bar magnets and horseshoe magnets can all be coated in zinc, which provides the magnets with corrosion resistance as well as being relatively cheap to use.
The zinc coating works as a sacrificial coat for the magnet – this means that the layer of zinc will wear off before allowing the magnet to corrode. Zinc is a natural water barrier, therefore if no water can get to the magnet then there will be no corrosion.
