HSMAG Neodymium Magnet Advantages
High Performance: The high performance HangSeng Magnets can reach: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.
High Consistency: The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67. The consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%.
High Working Temperature: The magnets of HangSeng can satisfy the working temperature requirements with excellent temperature resistance. The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications.
High Anti-Corrosion: The perfect coating of HangSeng Magnets can meet many anti-corrosion requirements. The salt spray test and humidity heat test of the high anti-corrosion coating Nickel+Copper+Epoxy is typically more than 1000 hours.
Low Weight Loss: The super-high magnets of HangSeng have a long lifetime with the following specifications; PCT: 130℃.humidity 100%.vapor pressure 2.7bar, 20days.average low weight loss <2 mg/cm2.
Neodymium Magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). The NdFeB magnets are the strongest type of rare earth magnet commercially available and are manufactured in a wide range of shapes, sizes and grades.
The NdFeB magnets are anisotropic sintered neodymium iron boron magnets – the alloy is jet milled to a fine powder.The magnetization diraction depends on the element of raw material.The Neodymium magnet are then sintered to fuse the powder together before final machining and magnetising produces the completed super strength Neodymium magnet.
Sintered NdFeB magnets are the most powerful magnets known. Maximum allowed temperature varies, but is up to 240°C for some grades. This maximum temperature is important, because usually the price of the magnet increase with temperature. The magnets consists of powder compacted in a magnetic field therefore they have process-fixed and limited magnetizing directions. Usually the magnetic field-lines have to be parallel in the material.
• Highest magnet strength available
• High resistance to demagnetization
• Operating temperature up to 240ºC
• Good at withstanding low temperatures (down to – 100ºC)
Corrosion protection is however always recommended for sintered neodymium magnets, because of the materials low corrosion resistance. The corrosion resistance of sintered NdFeB magnets can be compared to pure untreated iron.
A range of different coatings are available but sometimes complete encapsulation in i.e. stainless steel is preferable.
