Magnetic Direction

of the magnet has been determined during pressing. The magnetization direction of the finished product cannot be changed. Please be sure to confirm the required magnetization direction.

Coating

NdFeB magnet itself has poor corrosion resistance and oxidation resistance, so it needs surface electroplating coating. Different coatings are selected according to different use scenarios:

Certifications

Our company has passed a number of international authoritative quality and environmental system certifications, which is EN71/ROHS/REACH/ASTM/CPSIA/CHCC/CPSC/CA65/ISO and other authoritative certifications.

Characteristics

Neodymium channel magnets are stronger than ceramic channel magnets or standard neodymium block/bar shapes, as the steel channel concentrates most of the magnetic field to one side (the surface) of the magnet. They are plated with a triple layer of: Ni-Cu-Ni (Nickel+Copper+Nickel), using an electrolytic based process for maximum protection against corrosion and oxidation.

Pull Information

The approximate pull info listed is for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.

Applications

Channel magnets can be used in both indoor & outdoor applications, they are ideal for industrial & consumer mounting holding & fixing applications where high-magnetic strength is required.
