Strontium and Barium Permanent Ferrite Magnets

One of the standout features of these ferrite magnets is their excellent chemical stability. They are highly resistant to corrosion and oxidation, making them suitable for use in humid, dusty, or even mildly corrosive settings. This resistance ensures that motors equipped with these magnets maintain reliable operation over extended periods, reducing the risk of performance degradation due to environmental factors.​
In terms of magnetic properties, strontium and barium permanent ferrite magnets provide a balanced combination of remanence and coercivity. While their magnetic strength is not as high as that of neodymium magnets, they offer sufficient magnetic force for many standard motor applications, such as household appliances, power tools, and automotive auxiliary motors. Their moderate coercivity allows them to retain magnetism well under normal operating conditions, ensuring steady motor output.​
Cost - effectiveness is another key advantage. Compared to rare - earth magnets, strontium and barium permanent ferrite magnets are more economically viable, making them an attractive choice for large - scale production and cost - sensitive projects. This affordability does not come at the expense of durability; these magnets have a long service life, contributing to lower overall lifecycle costs for the motors they power.​
These magnets also exhibit good temperature stability. They can function effectively within a relatively wide temperature range, making them suitable for motors used in both high - temperature industrial environments and cooler consumer product settings. This versatility expands their application scope across various industries.​
