Very strong and solid 1/2" diameter discs in grade N52. They are a great mid-sized general purpose magnet.

This size is also available in grade N42 as part number D82, in grade N52 with Black Nickel finish as part number D82B-N52, in grade N42 with a Black Epoxy coating as part number D82E, diametrically magnetized as part number D82DIA, and in High Temp grade N42SH as part number D82SH.

Need to increase the force? If your application allows it, placing the D82-N52 in a NSC82 steel cup will result in a pull force nearly 4x the pull force case 1 strength!
