At FIRST4MAGNETS we stock a wide range of ultra-thin disc magnets which are just 1mm (0.04") thick or less. The majority of our 1mm (0.04") thick disc magnets are made from an alloy of neodymium-iron-boron (NdFeB) as this is the strongest magnetic material currently available to buy, therefore, despite their tiny size they generate an incredible magnetic pull. Their size, thickness and strength make them commonly used in many technology products including smartphones, hard drives, laptops and TVs. They are also popular for arts and crafts.
