This 43mm dia. rubber coated Neodymium (NdFeB) magnet has a Santoprene rubber coating which protects delicate surface areas. It has M3 female thread and a 50mm long screw-in handle. This Rare Earth magnet weighs 45 grams, has a pull force of 9kg, and is identified by the AMF magnet part number RCND43FH.
AMF has strong Neodymium based magnetic tools with a long detachable handle. This type of magnet provides extra leverage when applying or positioning often delicate vinyl media to metal surfaces. Strong, rubber coated, handle magnets are suitable for temporary holding applications where contact with steel surfaces occurs, and are a useful tool for positioning vinyl graphics to the side of vehicles prior to their permanent application. Due to the arrangement of magnets within the rubber coating, this type of handle magnet is ideal for use on surfaces which cannot be scratched, or where movement or slippage of a normal metal pot magnet system is not acceptable. It is a suitable tool for painted or varnished articles, or for applications where a strong magnetic force is needed without marking or scratching surfaces.

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.
The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
