OEM products These sintered NdFeB magnets features a cylindrical permanent alloy magnet housed in a stainless steel pot or case. These Sintered NdFeB magnets are particularly suitable for high volumn production of a wide variety of shape and size ranges. Precise dimensional control is achieved in both processed and usually the component does not require futher machining.
This cylinder type magnet can be in large length, about 50mm long.We can supply the rough, so that customers can cut the magnet into the length they need.
Available Coating: Nickel+Nickel, Copper+Nickel, Zinc, Nickel, Epoxy Black, Copper, Gold…
Available grade: Full grade N30-N50, include N,SH, UH, EH series
Magnetization direction: Radial and axial
Size: According to clients' request
Application feild: aviation, instruments, sensors, motors, speakers, microphones, electronics, magnetic separation, magnetic hook, magnetic pickup tools, cow magnets, magnetic health device(Therapy magnets), magnetic filter, magnetic rods etc.
