Product Code WP20

Product Description:

Our Steel Countersunk Washers are to be used as a metal contact point which magnets are attracted to. This non-magnetic washer has an Outer Diameter (OD) of 20mm, a Height (H) or Thickness (T) of 2mm, and an Inner Diameter (ID) of 5mm to 8.2mm. This product is identified by AMF Magnetics Part Number WP20. Price is per singular washer.

Uses for our Steel Countersunk Washers:

Made from high quality steel, with a nickel coating for corrosion resistance, our non-magnetic steel washers are used as a metal contact point which magnets are strongly attracted to. Featuring a 5mm (to 8.2mm) countersunk hole, perfect for use with flat-head screws.

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.
