These Grade N52 neodymium discs are considerably stronger than grade N42 discs of the same size. They are plated with Black Nickel which is actually more of a dark charcoal color than black. The DC6B-N52's are incredibly strong for their size and should not be taken lightly. Proper care and safety is required when handling these powerful discs.
This size is also available in grade N42 with our standard nickel plating as part number DC6
as well as diametrically magnetized
as part number DC6DIA
Note: Our "Black Nickel" plating is achieved by adding a special tint during the nickel plating process. The resulting color is not black. The appearance of these magnets is best described as grey, charcoal or gunmetal. Due to this unique process, slight variation in color may occur from order to order.
