SmCo and HRE-Free alternatives
SmCo sourcing and HRE-Free alternatives for high-temperature, corrosion-sensitive, and supply-sensitive applications.
High-temperature motors, sensors, medical, industrial controls
Material and performance notes
SmCo is used when temperature stability, demagnetization resistance, and corrosion resistance are important. HRE-Free alternatives can also be reviewed when the required performance, temperature margin, coating, geometry, and validation targets can be met.
SmCo remains useful for harsh temperature, corrosion-sensitive, and demagnetization-sensitive applications.
Sintered HRE-Free NdFeB options can be reviewed when the program needs the required output without restricted heavy rare earth content.
The review compares magnetic performance, operating temperature, corrosion protection, geometry, cost, validation needs, and sourcing risk.
