Neodymium Cube Magnets 7mm

Neodymium-iron-boron alloy let the 7mm mall cube magnets strong enough, the magnet to steel plate pull force varies from 4.33 LB to 6.43LB. However, the magnetic material is not rust-resistant, we usually deliver 7mm rare earth neodymium cube magnets with nickel plating, and other coatings like epoxy and gold are also popular coatings for it. You can use the strong cube neodymium magnet 7mm as magnetic pins for the whiteboard and fridge.

Characteristics Of Neodymium Cube Magnets 7mm

Remanence (Br): 7mm neodymium cube magnets N35 have remanence of 11700-12200Gs, and the same size of N52 is up to 14300-14800 Gs.

Coercivity (HcJ): 7mm neodymium cube magnets of different grade have different Hcj, the highest Hcj is 33Koe 2642 KA/m for AH-series.

Magnetic Energy/ (B-H)max:  The strongest neodymium cube magnets 7x7x7mm have(B-H)max of 52 MGoe.

Operating Temp.: That depends on material grade, and range from 80℃ to 230℃.

Available Coating: Nickel, epoxy and gold are the most widely used coating for these neodymium cube magnets for sale.
