Neodymium Block Magnet - 5mm x 5mm x 4mm N50

Magnetic Product Description:

This Rare Earth block magnet has a length of 5mm, a width of 5mm and a thickness of 4mm. It is identified by the AMF magnet part number B-W5H4L5-N50.

Uses for our rare earth block magnets:

Neodymium magnets are by far the most popular and it's no surprise why when you consider the superior strength to size ratio they provide. Since its development during the 1980s, Neodymium has largely replaced more traditional types of magnets that required more magnetic material to produce the equivalent magnetic properties. Just shy of a cube in shape, this small rare earth block is a handy dimension for those trying to create a magnetic connection within a confined space. Often referred to as silver magnets, Neodymium magnets normally have a Nickel coating that gives them a chrome-like surface. Craftspeople working with handicrafts such as woodworking love these tiny little square magnets as they are perfect for embedding as secret closing and joining mechanisms.

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.
