4x7mm is a popular size for small neodymium rod (cylinder)magnets, rare earth element makes the magnet more powerful than other magnetic material of the same size, and the magnetic force of different grade range from 1.2LB to 1.78 LB. Nickel-copper-nickel coating is common for 4x7mm neodymium rod magnets. Other surface coatings can be customized. We supply rare earth neodymium cylinders 4x7mm for many magnet distributors for a long time. Small neodymium rod magnets are used for various electronics and handcrafts.
