They are astonishingly powerful in size and have countless uses. They are magnetized by thickness. These neodymium disk magnets with a diameter of 20 millimeters each have a three-layer coating of nickel, copper, and nickel to prevent corrosion. br br Regarding dimensions: These disc magnets have a diameter of 0.79 inches (20 millimeters) and a thickness of 0.08 inches (2 millimeters). br br Regarding usage: Our neodymium magnets are typically used for creative applications such as model and theater design, furniture production, exhibition stands, and packaging. They also have many applications in engineering and manufacturing, requiring compact dimensions and maximum strength. More importantly, due to their resistance to demagnetization, they are an ideal choice for producing shock absorption or damping effects when used to repel other magnets. br br Please note: br 1. Strong small magnets heavy duty are composed of neodymium iron boron magnetic materials and coated with nickel copper nickel, forming a shiny and corrosion-resistant surface. The maximum operating temperature is 176 degrees Fahrenheit (80 degrees Celsius). br 2. Stay away from children and pets. br 3. Refrigerator magnets magnetic force is too strong, so be careful when separating them. br
