Pull Force* 576 gm

Weight 3 gm

Style Neodymium Cylinder

Gauss 6318

Grade N48

Coating Nickel (Ni)

Direction of Magnetisation Axially

Dimensions Height:4mm, Diameter:4mm

*Measured against up to 10mm mild steel.

Magnetic Product Description:

This popular rare earth cylinder has a diameter of 4mm and a height of 4mm. It is an N48 grade rare earth magnet. It has a magnetic flux reading of 6318 Gauss and a pull force of 0.576kg. It is identified by the AMF magnet part number C-D4H4-N48.

Uses for our rare earth cylinder magnets:

Small magnets that are cylindrical in shape are suited to placement inside circular drill holes or round recesses in plastic. They can then act as an attachment point for metal or make a closure mechanism with a magnet with the opposite pole exposed. The magnet can be glued in position or held in place with a thin covering which the magnetic field is able to penetrate.

Tiny magnetic closures and magnetic joins of this type are increasing in popularity with hobbyists, model makers and fashion accessory designers. The magnetic field is virtually invisible and far less conspicuous than traditional fastening methods that use clips, buttons or pins. Also referred to as rod magnets, these small magnets have a strong pull force relative to other types of permanent magnets of the same size.

Rare earth magnets were first developed in the 1980s and have since become the magnet of choice for most commercial operations where heat is not a factor. For high temperature applications it is more appropriate to use Ferrite, Alnico or Samarium Cobalt.

Hi Aaron,

Thank you so much for taking the time to share your experience and for this fantastic 5 star review!

We're thrilled to hear these 4mm x 4mm N48 neodymium cylinder magnets are proving to be super strong for their compact size in your 3D printed fixtures and clips! It's wonderful when the right magnetic solution can take a good idea and make it truly great.

The smooth coating on these small but mighty magnets really does make them perfect for precision applications like yours, ensuring they integrate seamlessly into your 3D printed designs while providing reliable magnetic hold.

Your feedback about the perfect sizing means so much to us. Getting the dimensions just right for maker projects and custom fixtures is crucial, and it's fantastic to know these little powerhouses are delivering exactly what you need.

Thank you for choosing AMF Magnetics for your 3D printing and design projects!

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.
