Neodymium Countersunk Block Magnets

The rectangular neodymium magnet blocks with countersunk hole are give the name of  rare earth neodymium(NdFeB) countersunk block(rectangular) magnets,the countersunk hole make the block magnets mountable.The neodymium countersunk block magnets can be screwed onto other surface,and used as magnetic holders.

Surface Treatment of Rare Earth Strong Neodymium Magnet Blocks with Countersunk Hole

Rare earth neodymium(NdFeB) countersunk block magnets are not rust-proof and easy to corrode, and their surface needs to be coated for durable, generally including zinc plating, nickel, environmental protection zinc, environmental protection nickel, nickel copper-nickel, environmental protection nickel copper-nickel, epoxy coating, etc.

The Magnetization Direction of Rare Earth Strong Rectangular Neodymium Magnet with Countersunk Hole

The magnetized direction of powerful neodymium(NdFeB) countersunk block magnets generally axially magnetized and magnetized through-hole direction, other magnetization direction is determined by the required working face. Please let us know which side is N or S-pole when you order strong neodymium countersunk block magnets.

Custom Rare Earth Strong Block Magnets with Mounting Holes

Neodymium rare earth countersunk rectangular(block) magnets are custom rare earth magnets, due to the good machinability of sintered Nd-Fe-B material, it can be customized into neodymium(NdFeB) block magnet with countersunk hole in different sizes,mould is not necessary for customizing neodymium block magnets with countersunk mounting holes.We can make all small and large neodymium countersunk block magnets for any quantity.
