Neodymium Cube Magnets 3mm

The small 3mm cube magnets are made of rare earth neodymium-which makes them powerful. To increase its durability, the surface is coated with a rust-proof coating. The magnetic pull force (magnet to steel plate) of 3x3 cube magnets varies from 0.63 LB to 0.93 LB, which depends on the grade. The small and powerful 3x3 magnetic cubes are used for making handicrafts.

Characteristics Of Neodymium Cube Magnets 3mm

Remanence (Br): The remanence of 3mm cube magnets is 11700-12200Gs for N35 and 14300-14800 Gs for N52.

Coercivity (HcJ): Hcj of 3x3 cube magnets varies according to the grade. Up to 33Koe 2642 KA/m for AH-series.

Magnetic Energy/ (B-H)max: (B-H)max is up to 52 MGoe for N52 neodymium cube magnets.

Operating Temp.: It varies according to material grade, ranging from 80℃ to 230℃.

Available Coating: Rust-proof coating like as nickel, epoxy and gold are usually made on 3x3 magnetic cubes.
