Sector Segment Samarium Cobalt Permanent Magnet Feature:
Shape: Sector, Segment
Grade: SmCo5, Sm2Co17
Coating: Without
Size: According to customer’s requirements
Characteristics：Good coercivity, Good temperature stability, Corrosion protection, rust prevention and high temperature resistance
Selling point: High uniformity, super thermo-stability & excellent corrosion resistance
SmCo is a kind of rare earth permanent magnet, whose magnetic strength is second only to NdFeB magnet. It has high coercivity (Hcj), high temperature resistance and good corrosion resistance. Samarium cobalt is more suitable for working in high-temperature environment. Samarium Cobalt magnet (SmCo) has two component ratios, SmCo5 and Sm2Co17.
We can provide our customers with customized samarium cobalt products and related solutions, which are highly resistant to corrosion without coating. Custom Plate Block SmCo Magnet
Customized Shapes: Block, Cylinder/Disc, Ring/Tube, Segment/Tile/Arc/Sector, Special Shapes
Because of high temperature resistance and good corrosion resistance, SmCo is used in electroacoustic devices, motors, measuring instruments, microwave devices, machinery, sensor, etc.

Features:
1. Excellent Coercity
2. Nice temperature Stability
3. Due to price sensitivity of cobalt, its price is expensive and easy to fluctuate
Production Process of Samarium Cobalt Permanent Magnet:
Powder process→ Pressing→ Sintering → Magnetic property test → cutting → finished products
Samarium cobalt materials are commonly processed under un-magnetized circumstances, with diamond grind wheel and wet fine grinding, which is necessary. Because of low ignition temperature, samarium cobalt must not be dry completely. Just a small spark or static electricity in production can easily trigger a fire, with extremely high temperature, which is hard to control.
Main Hazards:
Samarium cobalt magnets are brittle. Please kindly protect your eyes, fingers and body when dealing with them.
