20x20x20mm cube neodymium magnets

The cube magnet on the picture is made from neodymium magnetic material. Cube magnets are special block magnets, the size of the neodymium magnet cube is 20x20x20mm, it has very powerful magnetic force.

The 20mm cube magnets are made of Nd-Fe-B alloy,they have 17-25 kgs magnetic pulling force. Almost all grades and platings are available for 20x20x20mm cube neodymium magnets.There are technical dates of grade N45 and plated with Ni-Cu-Ni on below table.We deliver such strong neodymium cube magnets with thick plastic spacers,which make it easy to be separated.

Available Grades of 20mm cube neodymium magnets:  N35-N52, 33M-50M,35H-48H,35SH-45SH,28UH-40UH,28EH-38EH,28AH-33AH

Surface Treatment of 20mm neoydmium cube magnets: NiCuNi, Zn, NiCu+Sn, NiCu+Ag, NiCu+Au,NiCu+Epoxy, Parylene, Plastic coated, Rubber coated
