Neodymium Block Magnet - 25mm x 12.5mm x 75mm | N45

Magnetic Product Description:

This Rare Earth block magnet has a length of 75mm, a width of 25mm and a thickness of 12.5mm. It is identified by the AMF magnet part number B-W25H12.5L75-N45.


Uses for our strong Rare Earth block magnets:

Square, flat Neodymium Block magnets have excellent holding ability when the flat, wide pole surfaces are used to bond with a metal surface. Alternatively, the thin, narrow, non-pole edge of this powerful rectangular magnet can also be used to hold items to a metal surface but make the magnet much easier and quicker to remove or relocate when needed. Considerable care in handling the strong magnet is required to protect the magnet from harsh or sudden impact with a metal surface which can result in the magnet breaking and sustaining irreparable damage. The N45 Grade Neodymium power that is delivered to the wide North and South pole surfaces of this block is relatively high in value and gives the block extremely strong holding ability.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

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.
