•Magnetic Strength: The most powerful commercially produced magnets.
•Grades Available: Grades 35, 40, 42, and 45 are commonly available. (These numbers are an indicator of the strength of the magnet.) The highest grades available are in the 55 range.
•Physical Strength: Hard and fairly brittle - can chip or break if dropped or if they snap together.
•How they behave with temperature: Should not be used above 130° C (240° F) without careful magnetic circuit design.
•Magnet surface: Neodymium magnets that are not protected with a surface coating (such as plating) may rust in humid conditions.
•Relative cost: Neodymium magnets are a little more costly than the ceramic types, but pack a much stronger punch.
•Care tips: Take care when handling these magnets - especially larger magnets. They are very strong and can snap together or to a steel surface with a strong force! Be careful not to pinch your finger between magnets.
•Assembly tips: Neodymium magnets are often assembled into products using "superglues" such as Loctite 325. Always ensure that bonding surfaces are clean and dry prior to bonding.
