Neodymium Block - 20mm x 20mm x 5mm

Rated 5.0 out of 5
Based on 1 review
Product Code 22015A
Pull Force* 8.3 kg
Weight 15 gm
Style Neodymium square Block magnet
Coating Nickel (NiCuNi)
Direction of Magnetisation Axially magnetised
Dimensions Width:20mm, Height:5mm, Length:20mm

Magnetic Product Description:

This block magnet has a 20mm width and length with a thickness of 5mm. It has a magnetic flux of 2581Gauss and a pull force of 8.3 kilos against 5mm mild steel.It is identified by the AMF magnet part number 22015A.

Uses for our rare earth block magnets:

This Rare Earth magnet has two square flat surfaces that represent the North and South magnetic poles and has a low height profile. Low height dimension magnets have less overall strength than a thicker magnet but in some applications this is desirable. Easy-to-release bond is attractive to a wide range of users including window furnishing manufacturers, cabinetmakers, costume and fashion designers and for crafting and handyman purposes,

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.

Great product

Great for the project I was doing, attaching solar panels to my iron roof. Far exceeded my expectations. I will certainly be purchasing from you again.
