DescriptionMaterial quality : Neodymium magnetsModel Number: Permanent N35Application: Industrial MagnetPlating: Ni-Cu-Ni ( Nickel )Tolerance: 0~1mmMax Operating Temperature: 80 degree / 176 Fahrenheit degreeUnit size: millimetre (mm.) 1mm=0.0394inchNOTICES1. The NdFeB magnet is sold by size, the unit of measurement is millimetre, please pay attention to the size.2.Due to the particularity of the magnet and manual measurement, there may be an error within 1mm.3. Related electronic products, such as Mechanical watchs ,bank cards, mobile phones, computers, televisions, pacemakers, etc., they are easily affected by neodymium magnets, please keep a certain distance to avoid unnecessary losses.4. When connecting two magnets, draw them close to each other slowly and gently. The magnetic properties of NdFeB magnets are incredible, please be careful not to hurt your hands when using them.5. NdFeB magnets are fragile, the characteristics are hard and brittle, especially large-size products, strips and thin slices, separate the magnet, please carefully shift staggered, must not break the hard pry, so as not to damage the product or injured , Separated to maintain a certain distance, so as not to the collision, damage to the product, or even dangerous.6. NdFeB magnet surface coating protection, with a certain anti-rust corrosion resistance, but if not used in time, be sure to keep away from the high temperature and corrosive environment.
