Product Description

This product measures 3/8" in diameter and 1" in thickness and is made of a grade N50 neodymium, iron, and boron magnetic alloy blend. This magnetic blend is patent licensed and made under the ISO 9001 quality systems. These magnets are plated in a nickel-copper-nickel coating for a shiny corrosion-resistant finish. The poles are on the curved surfaces. The pull force is 18 lbs. This is a great item for use in personal projects in addition to crafts and closures. They are also good at keeping objects secured or fastened to a ferrous surface.
