Square & Rectangular Ferrite Magnets

Square and rectangular ferrite magnets are sintered permanent ferrite magnets. They are shaped via high-temperature sintering with iron oxide and strontium carbonate as main raw materials, forming neat rectangular blocks. They feature high hardness, outstanding corrosion resistance, rust-free performance and low cost.

They deliver stable magnetic force and excellent demagnetization resistance, making them universal permanent magnets for industrial use. The material is relatively brittle, so dropping from heights and heavy impact are prohibited. Their flat four-sided shape allows easy installation and positioning with tight adhesion to flat surfaces. They are widely applied for magnetic fixation of various equipment, motor segment bases, tooling positioning and other applications.

Product Advantages

1.High cost performance: The bulk purchase cost is much lower than NdFeB, SmCo and Alnico magnets.

2.Acid, alkali and oxidation resistant; free from corrosion and rust even after long-term service in humid environments.

3.Excellent temperature stability; hardly demagnetized when used in common motors and heat-generating equipment.

4.Large flat bonding area with evenly distributed magnetic attraction. The rectangular shape facilitates screw fixation and slot installation.

5.Secondary processing available: drilling, chamfering, surface grinding and cutting to fit non-standard mounting structures.

Production Process

Raw material mixing → pre-sintering → crushing & powder preparation → mold pressing into square blanks → high-temperature sintering → surface grinding / chamfering → magnetization → finished product inspection
