Magnet Disc 20x3mm N38 Ni

Magnet Disc 20x3mm N38 Ni

Neodymium discs are powerful magnets, ideal for holding or hanging metal objects and other magnetic applications. Made from a neodymium, iron, and boron alloy, these magnets are compact yet extremely strong, with permanent magnetic properties and high energy output.

Features

• Shape: disc / round
• Coating/Plating: Ni-Cu-Ni (Nickel)
• Grading: N38
• Tolerance: +/- 0.1
• Maximum temperature: N38 grading magnets can work in an environment that has a maximum operating temperature no greater than 80°C.
• Pulling Force: 3.92 kg
• Colour: Silver

Pros

• Best power to weight ratio of all magnets.
• High resistance to demagnetization.
• Magnetic pulling force of 3.92 kg

Cons

• Magnetism starts to decrease (and can be permanently lost) at 80°C.
• Low corrosion resistance. (If the plating is damaged)
• Will rust when exposed to wet elements.
• Brittle (May break, crack, or chip upon sudden collisions with other magnets or metals.)
• Drilling magnets causes magnet to shatter.
