Multi Polar Sintered Neodymium Magnet Radial Ring Magnet With Gold Coating

High Grade N35-N52 Multi-Polar Sintered Neodymium Magnet With High Magnetic Flux Density

Product Description:

Sintered Neodymium Magnets are a kind of permanent magnets made of Neodymium-Iron-Boron (NdFeB) magnetic alloy compound. Due to their extremely high magnetic flux density and outstanding stability, they are widely used in various industrial applications. The sintered neo magnet can be customized to meet customer's specific requirements in terms of size, pull force, and magnetic performance. High quality neodymium material used in the manufacturing process ensures the magnets have superior magnetic flux density and high pull force. With stable magnetic performance, sintered neo magnets are long-lasting and reliable.

Manufacturing process for magnets (outline):

Mixing1.Mix the ingredients.
Melting2.Dissolve the mixture at high temperature and prepare an alloy.
Fine pulverization3.Turn the alloy into fine powder.
Molding in a magnetic field4.When pressing the fine powder, apply a magnetic field to it and prepare
a molded product of powder with aligned directions of magnetization.
Sintering and heat treatment5.Sinter the product at about 1,100℃, and then subject it to heat treatment at
about 600℃ to increase its magnetic characteristics.
Processing6.Process the manufactured magnet base material and finish it into the product shape.
Surface treatment7.Subject the product to surface treatment in order to make it rustproof.
Magnetization8.Apply a magnetic field to give the magnet magnetism.
