Neodymium Block Magnet - 25.4mm x 3.175mm x 50.8mm | N52

Magnetic Product Description:

This rare earth block magnet has a length of 50.8mm, a width of 25.4mm and a height of 3.175mm. It is identified by the AMF magnet part number B-W25.4H3.175L50.8-N52.

Uses for our strong rare earth block magnets:

Extremely powerful Neodymium magnets are popular throughout the industrial world and are also increasing in popularity with DIY enthusiasts and small, home-based businesses This large Neodymium block has 1-inch x 2- inch US dimensions and contains magnetic material of the highest N52 Grade. Rectangular magnets are generally lower in height and easier than more bulky magnets to fit inside the casing of electronic goods as well as other less complex products. Compact Neodymium magnets can be hidden inside the covering of a product so it bonds with a metal surface in a stylish non-visible and non-mechanical way. Invisible magnetic bonding can provide an innovative and far more practical way to store your goods. Magnetically attaching tools or other important items to metal surfaces on cars, work trucks, boats and metal surfaces in the workplace means the items you need are always organised and are fast and easy to access.

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.
