These discs are a bit different than most of the magnets we stock. They are plated with Black Nickel and are grade N52. The Black Nickel is actually more of a dark charcoal color than black. It is a little more corrosion resistant than regular nickel, but the main reason we decided to stock them is because they look neat. Made of N52 material, these magnets are very strong and will pinch hard if you are not careful. Their strength makes them a little less "user friendly" than most of our N42 magnets. Overall, they are neat looking and wicked strong.
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.
This size is also available in grade N42 with standard Nickel plating as part number D84
