Magnetic Product Description:

This rare earth disc magnet has a diameter of 8mm and a height of 5mm. It is encased in red and black plastic. It has a magnetic flux reading of 4824 Gauss. It is identified by the AMF magnet part number 20026.

Uses for our rare earth disc magnets:

Plastic building materials are replacing traditional building materials at an ever-increasing pace. Able to be cut with computer-assisted laser beam precision, the huge plastics family competes with, or out-competes, metal, stone, timber and fabric on price, weight, efficiency and flexibility. No wonder plastics are having such impact.

While the traditional building materials might be left on the shelf, super lightweight 8mmx5mm plastic housing red and black coloured magnets continue to be pressed into service in conjunction with the more modern plastic building materials. Wherever layering of different materials is found, magnets will be making their presence felt.The architectural profession has always been early adopters of new materials and more efficient ways of doing the same thing: like simpler, user-friendly designs or keeping the weather at bay. While materials and designs have changed beyond recognition from only a generation ago, magnets have made the successful transition into modern-day construction methods.

These Plastic Housed Red and Black Neo Magnets are N42 Grade which will compensate the loss of holding power caused by the plastic case.They are ideal for outdoor use or situations exposed to water. North pole denoted by Black, South by Red. Often used in science classes, wall map location markers and offices. Also used in warehouses to indicate stock status and levels by attaching the red or black face to pallet racks or shelving.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.

Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.

Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
