SmCo Rod Magnets are a type of magnetic material made from rare earth metal samarium and strategic metal cobalt-main elements, with iron, copper, zirconium, and praseodymium, and produced by a serial of process melting, milling, pressing, sintering and aging. It has high magnetic properties (high energy product, high coercivity, high remanence), very low-temperature coefficient (-0.030% / °C), high working temperature (Maximum working temperature reaches 350°C), no negative temperature limitation, and excellent corrosion resistance. At working temperature above180°C, its maximum energy product, temperature stability, and chemical stability are better than NdFeB material.
Strong SmCo Cylindrical Magnet
Samarium Cobalt cylinder magnets are great for use in many applications, especially where temperatures above 250C are present. This includes applications such as aerospace magnets, medical magnets, automotive magnets, sensor magnets, and consumer electronics magnets.

Rod Cylinder Precision SmCo Magnets
Cylinder Magnets have a longer magnetic field reach when magnetized through the length. This makes them a good option as a sensor magnet where the distance between the sensor and magnet is further. Or, for a holding application where the reach of the magnetic field will pull the magnet toward the ferrous material at a great distance.
