What are the main components of sintered permanent ferrite magnetic materials? Which ingredient has the largest proportion? This is the question that Courage Magnet Xiaofu, a magnet manufacturer, told you today.
The most sintered ferrite is Fe2O3. The following figure shows the details and proportions of ferrite materials.

1. Fe2O3 accounts for 85%
2. SrO accounts for 13.5%
3. CaO accounts for 0.8%
4. Al2O3+SiO2 accounts for 0.7%
Because ferrite magnets have good temperature resistance, corrosion resistance, low price and moderate performance, they have become the most widely used permanent magnets in all walks of life.
