Super Strong N42 Disc Magnets 20mm x 3mm – 4.6kg Pull Force
High-Performance Neodymium Magnets
Neodymium, discovered in 1885, became essential in the early 1980s when alloyed with iron and boron to form the powerful neodymium magnets used today.
The term “rare earth magnets” refers to a specific group of elements in the periodic table, not their scarcity. Neodymium is as common as tin or lead.
Neodymium magnets are far more powerful than traditional ferrite magnets. Their strength is measured by the “N” number; the higher the number, the stronger the magnet. N numbers range from N27 to N52.
Key Features:
- Grade: N42
- Plating: Ni-Cu-Ni (Nickel Copper Nickel)
- Max Temperature: 80°C / 176°F
- Material: NdFeB
- Color: Silver
- Magnetic Face Diameter: 20mm
- Thickness: 3mm (5mm Countersunk)
Care must be taken when handling these fishing magnets as there is a danger of trapped fingers, pinched skin and flying shards of metal if carelessly handled. Never allow magnets to jump together or to jump to steel as they will likely shatter. Suitable for usage up to a maximum of 80 degree Centigrade. Always keep magnets away from items that may be damaged by the powerful magnetic field such as credit cards, computers, mobile phones, cd’s. Not to be handled near to or by people with Pace makers or other medical devices. The actual pull strengths will vary depending on other variables such as: Steel thickness( the thinner the steel the lower the pull strength ), Steel Quality( for example pitted/corroded ), Surface finish( painted, powder coated will result in a reduced pull force ).
