This is one of our most popular sizes. This is a great size for general purpose hanging and a wide variety of magnetic applications. This magnet was supposed to be N52, but it didn't meet our strict quality tests, so we are selling them at a discount! They test more like a strong N48 grade.

This size is also available in grade N42, as part number D42, N52 as D42-N52, in grade N52 with black nickel plating as D42B-N52 , in grade N42 with black epoxy coating as D42E , and diametrically magnetized as D42DIA.
