Sintered neodymium N52 grade material is highest in China. Our manufacturer has the advance equipment like strip casting,hydrogen decrepition and continuous sintering furnace to ensure the quality of N52 material.

This N52 block magnet is very strong for holding. We usually mark north pole with red dot or south pole with green dot to indicate polarity on magnets.

To ease customer to glue the magnet, we also usually sand one side of magnet surface to be rough,but other sides are shining and smoothy with nickel plating.
