Five Advantages Of Products
high machanical strength
adjustablr magnetic properties
dimensional precision
elastic magnetization
composite molding

Our micro magnets for cylinders with tiny hole or without hole are appreciated by our customers for their quality and regularity. Mini Micro Rare Earth SmCo Ring Magnets
The machines we use allow us to work both with a static shaping process and with a continuous flow technique according to the sizes required. Our working tools are diamond grinding wheel of different types and grain according to the piece and to the work to carry out, and the roughness of the surfaces are comprised between Ra of 0.2μ and 0.5μ.

We specialize in thin-walled and slot-opening miniature ring magnet through laser incising, drilling and processing SmCo material. Serial products of SmCo ring magnets, precious stone bearings, etc. are widely applied in fields of miniature motor, optical communication, instrument and meter, watch, electro acoustic, etc.

Applications of Samarium Cobalt Magnets
Computer disc drives
Sensors
Traveling wave tubes
Linear actuators
Satellite systems
Motors where temporary stability is vital

Attributes of Samarium Cobalt Material
High resistance to demagnetization
High energy (magnetic strength is strong for its size)
Good temperature stability
Expensive material (cobalt is market price sensitive)
