Our micro magnets for cylinders with tiny hole or without hole are appreciated by our customers for their quality and regularity.
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.
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)
For as pressed material, tolerance on the thickness (direction of magnetization) is ± .005. Other dimensions are ± 2.5% or ± .010, whichever is greater. According to IMA standards, visual imperfections such as hairline cracks, porosity and minor chips are commonly found in sintered metallic magnets. A chipped edge is considered acceptable if no more than 10% of the surface is missing. Cracks are acceptable as long as they do not extend across more than 50% of pole surface.
