Samarium Cobalt magnets Series 1-5 (SmCo5)
These samarium cobalt magnet alloys have one atom of rare earth Samarium and five atoms of Cobalt. By weight this samarium cobalt magnet alloy will typically contain 36% Samarium with the balance Cobalt. The energy products of these samarium cobalt alloys range from 16 MGOe to 25 MGOe. These Samarium Cobalt magnets generally have a reversible temperature coefficient of -0.05%/°C. Saturation magnetization can be achieved with a moderate magnetizing field. This series of Samarium Cobalt magnet is easier to calibrate to a specific magnetic field than the SmCo 2-17 series magnets.

In the presence of a moderately strong magnetic field, unmagnetized magnets of this series will try to align its orietation axis to the magnetic field. Unmagnetized magnets of this series when exposed to moderately strong fields will get slightly magnetized. This can be an issue if post processing requires that the magnet be plated or coated. The slight field that the magnet picks up can attract debris during the plating or coating process causing for a potential plating or coating failure or a mechanically out of tolerance condition.

Machining or grinding this magnet by the user is discouraged. This material must be ground using diamond cutting and grinding tools and a significant amount of water based coolant. Dry ground powder can iqnite spontaneously with a small spark.

Samarium cobalt magnets can work under higher working temperature than neodymium. The cost of SmCo material is the most expensive, so SmCo magnets are recommended only when high temperature working environment is concerned.

SmCo permanent magnets characteristics:
1. SmCo permanent magnets have high magnetic energy product and high coercive force. The magnetic performance is much better than Alnico and ferrite permanent magnet. The Max. energy product is up to 239kJ/m3(30MGOe), which is three times of Alnico8 permanent magnet’s and eight times of ferrite permanent magnet’s (Y40), so the components made of SmCo material could be small, light and stable in property. It is widely applied to electro acoustic & telecommunication apparatus, electric motors, measure meters, peg-top, electronic watch, microwave apparatus, magnetic mechanism, sensor and other static or dynamic magnetic routes.

2. The curie temp. of SmCo permanent magnets is high and its temp. Coeff. is low. They are suitable for the application at 300℃ high temperature.

3. SmCo permanent magnets’ rigidity strength, tensile strength and pressure strength is low, so they are more fragile and easier to crack. The main ingredient of SmCo permanent magnets are metal cobalt(Co≥99.95%), so the price is higher. Good Corrosion Resistance Performance Samarium Motor Magnet

4. SmCo magnets have good corrosion resistance performance, therefore generally the products do not need coating or plating.
