ISO STANDARD

SAMARIUM COBALT MAGNETS SMCO Magnets Samarium–cobalt magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt In terms of magnetic strength, they are almost similar to NEO magnets but have superior temperature resistance and coercivity. Difference between Neodymium and Smco Magnets:

Properties	Neodymium Magnets	Smco Magnets
Remanence (T)	1–1.3	0.82–1.16
Coercivity (MA/m)	0.875–1.99	0.493–1.59
Relative permeability	1.05	1.05
Temperature coefficient of remanence (%/K)	−0.12	−0.03
Temperature coefficient of coercivity (%/K)	−0.55..–0.65	−0.15..–0.30
Curie temperature (C)	320	800
Density (g/cm³)	7.3–7.5	8.2–8.4
CTE, magnetizing direction (1/K)	5.2×10⁻⁶	5.2×10⁻⁶
CTE, normal to magnetizing direction (1/K)	−0.8×10⁻⁶	11×10⁻⁶
Flexural strength (N/mm2)	250	150
Compressive strength (N/mm2)	1100	800
Tensile strength (N/mm2)	75	35
Vickers hardness (HV)	550–650	500–550
Electrical resistivity (Ω·cm)	(110–170)×10⁻⁶	86×10⁻⁶

We can supply in different shapes and sizes as per your need.

Application

High-end electric motors used in the more competitive classes in slotcar racing
Turbomachinery
Traveling-wave tube field magnets
Applications that will require the system to function at cryogenic temperatures or very hot temperatures (over 180C)
Applications in which performance is required to be consistent with temperature change
Benchtop NMR spectrometers
Guitar Pick ups
Samarium - cobalt magnet has a strong resistance to corrosion and oxidation resistance, usually do not need to be coated can be widely used in high temperature and poor working conditions

Production

Raw materials are melted in an induction furnace filled with argon gas.
The mixture is cast into a mold and cooled with water to form an ingot.
The ingot is pulverized and the particles are further milled to further reduce the particle size.
The resulting powder is pressed in a die of desired shape, in a magnetic field to orient the magnetic field of the particles.
Sintering is applied at a temperature of 1100 C–1250 C, followed by solution treatment at 1100C–1200 C and tempering is finally performed on the magnet at about 700C–900C.
It then is ground and further magnetized to increase its magnetic properties.
The finished product is tested, inspected and packed.
