1.Cheap price,high quality and fast delivery time. 2.Professional 3.Our certificate: ISO9001:2008 Characteristics of NdFeB Magnet Physical Properties: 1. Neodymium Magnets are the strongest magnets in the world. They can lift up to 1000 times theirs own weight. 2. Neodymium Magnets are easy to machine, compared to Alnico and SmCo Magnets 3. Neodymium Magnets are with high resistance to demagnetization. 4. The maximum working temperature of magnet is changeable due to ratio of length and diameter and environment factors. 5. Compressive strength MPa: 1050, bending strength:290 6. The perfect coating of neodymium magnet 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 one month. 7. The super-high neodymium magnet has a long lifetime with the following specifications; PCT: 120°C, humidity 100%, vapor pressure 2 bar, 4-7 days, average low weight loss<3mg/cm2Looking for ideal Ring Magnets Radiation Manufacturer & supplier ?
