Magnetic Product Description:
This Rare Earth block magnet has a length of 15mm, a width of 12mm and a height of 4mm. This product has a black epoxy coating, a pull force of 3.9kg and is N50 grade. This product is identified by AMF Magnet part number 22011.
Uses for our Rare Earth Block Magnets with Epoxy Coating:
Rare Earth magnets are the strongest magnets available and have greatly influenced the design and manufacture of many of the world's commercial and consumer products since the proliferation of Neodymium in the 1980s. The standard Nickel coating on these powerful magnets is a cost-effective way of protecting the brittle Neodymium material in banal atmospheric conditions, however, extended periods of exposure to the fluctuations of the weather will eventually lead to corrosion and a breakdown of the Nickel coating, allowing the Neodymium core to deteriorate and eventually fail. To overcome this problem, AMF supplies a range of magnets that have a Black Epoxy coating. The Epoxy seals and protects the encased magnet from the elements and exposure to wind, abrasion, chemicals, salt air and enables magnetic hold to be sustained in underwater applications, harsh atmospheric conditions and general outdoor use. Epoxy coated magnets, like this axially magnetised Neodymium block, have greater durability and extended working life. This makes them an ideal alternative to nickel coated magnets in atmospheres of high humidity, marine environments and for numerous industrial and agricultural uses. The higher than average N50 Grade Neodymium material in this magnet will, to some extent, compensate for the reduction in magnetic strength that the Epoxy coating creates by widening the air gap between ferrous and magnetic surfaces.
