The thickened 20mm neodymium iron boron square magnet is a high-load, high-strength solid magnetic component developed for heavy-duty adsorption and high-power magnetic drive scenarios. Different from thin conventional magnets, this product adopts a 20mm thickened solid structure, which greatly improves the magnetic storage capacity and structural stability of the magnet. The thickened design makes the internal magnetic field density higher, the magnetic force more concentrated, and the adsorption load-bearing capacity greatly enhanced, which can easily meet the heavy-load fixing, strong adsorption and large-torque magnetic drive requirements of industrial equipment, and is a core heavy-duty magnetic component in industrial manufacturing.

In terms of core performance, the 20mm thickened square magnet has ultra-high magnetic energy storage and super strong bearing capacity. The thickened solid structure avoids the magnetic attenuation problem of thin magnets under heavy load, and the magnetic field penetrates deeply with strong adsorption force. It has excellent anti-vibration, anti-pressure and anti-impact capabilities, and will not deform, crack or demagnetize under long-term heavy-load working conditions. The square regular structure makes the stress uniform during use, the installation and fixing more stable, and the contact area larger, which effectively improves the adsorption stability and load-bearing limit. After high-pressure sintering and aging treatment, the product has stable internal structure, long service life and almost no natural demagnetization.

This thickened square magnet is widely used in heavy industrial equipment and large mechanical supporting scenarios. In the mechanical processing industry, it is used for heavy-duty magnetic chucks, CNC machine tool fixture magnetic components, mechanical equipment base fixing magnets and large mold adsorption parts, providing stable heavy-load positioning and fixing force for industrial processing. In the logistics and handling industry, it is applied to magnetic crane accessories, material handling magnetic suction tools and conveyor equipment magnetic fixing components, improving the efficiency of heavy material handling. In the new energy and machinery manufacturing industry, it is used for large motor rotor magnetic steel, mechanical power magnetic components and equipment shock absorption fixing parts.

The 20mm thickened neodymium iron boron square magnet has high structural strength and good environmental adaptability. The product can be customized with anti-corrosion treatments such as nickel plating and epoxy coating, which can adapt to harsh working environments such as humidity, dust and mild corrosion. The regular square structure is convenient for drilling, grooving and secondary processing, meeting the personalized installation and use requirements of different equipment. All products have passed strict load-bearing test, magnetic performance test and structural stability test, with reliable quality and stable performance. For heavy industrial scenarios that require high load-bearing, strong adsorption and long-term stable work, the 20mm thickened square magnet is the most reliable high-strength magnetic matching product.
