BeiLun Meank neodymium magnets 10mm x 5mm series is made of neodymium-a rare earth element on the periodic table, which makes the magnet amazingly powerful. The lowest grade 10mmx5mm rare earth neodymium disc magnets have 5.4 lbs magnetic pull strength (magnet to steel plate)
To prevent the 10mm x 5mm magnets from rusting, they are usually coated with Nickel-Copper-Nickel plating. Our strong round neodymium magnets 10 mm x 5mm are made of a brittle material, so they are not as durable as steel. They are more like brittle ceramics. They can crack and break if you let two magnets slam together, just like a brittle ceramic. This is true for the highest-grade magnetic material.
Remanence(Br): The remanence(Br) of neodymium magnets 10mm x 5mm is around 14500 Gs.
Hcj: Sintered neodymium disc magnets 10x5mm N52 is over 11 Koe（876 KA/m）.
Magnetic Energy/(B-H)max: The neodymium disc magnets 10mmx5mm series have a magnetic energy of 52 MGOe.
Working Temperature: 10x5mm round disc magnet neodymium N52 withstands temperatures under 80℃.
Corrosion Resistance: The neodymium magnets 10mm x 5mm series are not corrosion resistant; thus, rust-proof coating is needed.

Warning: Children are not allowed to play with neodymium disc magnets for sale without the supervision of parents, because they may swallow small magnets by mistake.
