Product Descriptions
Rare Earth Disc Magnets are compact, high-performance magnets engineered from neodymium (NdFeB), providing exceptional magnetic strength in a small, disc-shaped form. Their uniform axial magnetization ensures consistent magnetic fields, making them ideal for a wide range of applications, including industrial assembly, electronics, sensors, and holding or fastening systems.
Available in various diameters and thicknesses, these magnets are precision-manufactured to meet strict tolerances and are often coated with nickel, zinc, or epoxy to prevent corrosion and enhance durability. The symmetrical disc design allows for easy integration into automated production lines, while delivering maximum surface contact for optimal holding power.
