| Among those famous sintered alnico magnets manufacturers, it is a professional supplier in China, welcome to wholesale alnico pickup magnets, alnico speaker magnet, pick up 5 magnets, horseshoe magnet, pickup magnets from our factory.Customized Sintered Alnico MagnetsSintered Alnico magnets are formed by co***cting fine Alnico powder in a press and then sintering the co***cted powder into a solid magnet. The powdered mixture of contents is pressed into a die under tons of pressure. It is then sintered in a hydrogen atmosphere at 2300F and then cooled 鈥?either within a magnetic field or without a magnetic field. When cooled within the magnetic field it is known as an anisotropic magnet and when cooled outside of a magnetic field it is called an isotropic magnet. The sintering process is well suited to large volume production.SpecificationDimension 聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽 Tolerance Up to 0.125" Up to 3.18 mm 聽聽聽聽聽聽聽聽聽聽卤.005" .13 mm0.126" to 0.625" 3.20 to 15.88 mm 聽聽聽聽聽聽卤.010" .25 mm0.626" to 1.250" 15.90 to 31.75 mm 聽聽聽聽聽卤.015" .38 mmAdvantages and Disadvantages of Alnico Magnets路聽Alnico Br as high as NdFeB at room temperature.路聽Can be used up to 450-550 degrees C (842-932F).路聽Least variation in magnetic output with temperature change of any magnetic material.聽路聽Can be cast in very large sizes.路聽Sintered alnico is usually limited to small to medium sizes and simpler shapes.路聽Low coercivity (Hci) making them easy to demagnetise.路聽Complex cast alnico sometimes needs sand mold tooling which can be expensive if existing tooling is not available.Production Properties:聽聽Magnetic Property Parameters of Sintered Alnico GradesEquivalent M*** ClassRemanenceCoercive ForceCoercive ForceMaximum Energy ProductDensityReversible Temp.
