Applications:

Here we have our popular 1/4″ cubes with a sleek black nickel finish. The black nickel plating gives these magnets a shiny, charcoal-colored appearance. They are identical to the B444, with just a different color.

This size is also available in grade N42 with our standard Nickel plating under part number B444, in grade N52 under part number B444-N52, and with a 1/16″ hole through the center as part number B444-1.

Note: Our “Black Nickel” plating is achieved by adding a special tint during the nickel plating process. While the finish is not black, the magnets have a grey, charcoal, or gunmetal appearance. Due to this unique process, slight color variations may occur between orders.
