Magnetic Product Description:

This Neodymium Block has a length of 50 mm, a width of 20 mm and a height of 5 mm. It has the AMF Magnet part number CB-L50W20H5D8/D4. It is a handy size which can be used in many applications where a long, thin rare earth magnet is needed.


Uses for our strong neodymium rare earth block magnets:

Neodymium magnets are made from powerful rare earth minerals. This unique magnetic material gives Neodymium products their unrivaled magnetic strength. Neodymium Block magnets are available in square and rectangular shapes and an extensive range of sizes that are suitable for both domestic and commercial use. This large block magnet has two convenient countersunk holes that allow it to be permanently held in position with one or two tapered-head screws. This means the magnet can be attached to almost any surface, including those that are non-magnetic such as timber, plastic and masonry. This type of countersunk Block magnet is ideal for applications where a magnetically operated closure is required. The countersunk magnet can be attached on one side of an opening with screws, so when a metal striker plate enters its magnetic field, the two will bond together. Cupboards, drawers, doors and gates can be held in an open or closed position using this very practical countersunk magnet and the simple convenience of magnetic bonding.

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.
