What is a Permanent Ferrite Magnet<\/b><\/h2>\n

<\/p>\n

Permanent ferrite magnets are made from a composite material of ferrite, an iron oxide combined with elements such as strontium or barium. These magnets are produced by pressing and sintering the powder material at high temperatures. This manufacturing method gives ferrite magnets their unique magnetic properties.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Characteristics of Permanent Ferrite Magnets<\/b><\/h2>
\u00a0<\/div>

Corrosion resistance: Ferrite magnets are corrosion-resistant, making them suitable for use in humid environments or exposed to harsh outdoor conditions.<\/p>

Thermal stability: They offer good thermal stability, which means that they retain their magnetic properties over a wide range of temperatures.<\/p>

Affordable Price: Ferrite magnets are economical compared to other types of magnets, making them an attractive choice for many applications.<\/p>

High coercivity: They have a high magnetic capacity , which means that they require a significant magnetic force to demagnetize them, making them suitable for applications requiring long-term magnetic retention.<\/p>

Automatic dimentional control to garanty high quality<\/p>

All dimensional measurements are carried out on CMM. This makes it possible to measure all dimensions with high precision (radius, thickness, length, width, etc.) as well as all shape defects (symmetry, straightness, perpendicular, etc.). All key parameters are monitored by SPC (Statistical Process Control).<\/span><\/p>
