Disc Magnet

Product Detail Ndfeb rare earth permanent magnet has the characteristics of high remanence, high coercivity, high magnetic product energy and so on. Easy to process into various sizes. 1.Grade of NdFeB magnets. If your application is only at room temperature, the N-series is the best choice, with a maximum operating temperature of 80 degrees Celsius. In general, the N35 is relatively cost-effective, and the magnetic force is also relatively strong. But which level you choose depends on your pursuit or application of magnetism. The higher the resistance temperature of the magnet, the more expensive the price. For example, the N35 class and the N35M class have the same magnetic force, but the maximum operating temperature of the N35M is 100 degrees Celsius, and the N35 is only Celsius.

N42 D4x2mm nickel-plated magnet features axial magnetization and a residual induction of approximately 3500 Gauss. With a maximum operating temperature of 80°C, this compact magnet is perfect for sensors and electronic applications requiring strong magnetic performance and corrosion resistance.

Unlike gold, zinc and nickel, an epoxy magnet coating acts as an excellent barrier to salt, ambient air, water or moisture. But it's slightly more expensive than the first three alternatives. Although it is easy to scratch, with a thickness of 15-30 um, it has good adhesion to steel with magnetic glue. Epoxy coatings are mainly used in the Marine, motor, sensor, automotive and consumer goods industries.

Ndfeb High performance magnetic materials, we can manufacture a variety of sizes to meet your needs.

Common round NdFeB magnets, support 24H salt spray test as well as a maximum operating temperature of 80°C.

NdFeB round-shaped strong rare-earth permanent magnets are crucial components in many modern technologies due to their exceptional magnetic strength and versatility.

NdFeB round-shaped strong rare-earth permanent magnets are crucial components in many modern technologies due to their exceptional magnetic strength and versatility.

Round NdFeB magnet have a wide range of applications. Even at a very small size, it is strong enough for many tasks.

Neodymium disc magnet with 3M adhesive, can be easily fixed to non-metallic surfaces with adhesive. Because the adhesive is not resistant to high temperatures, please use it at normal temperatures.

This high-performance NdFeB magnet features a countersunk hole for easy mounting and a robust 10lb pull force. Measuring 20mm in diameter and 5mm in thickness, it’s ideal for various applications requiring strong magnetic strength. The nickel coating ensures durability and resistance to corrosion, making it perfect for industrial, DIY, and professional uses.

Sintered NdFeb permanent magnet materials are divided into six types of products according to the coercivity of magnetic pole strength: low coercivity (without letters), medium coercivity M, high coercivity H, extremely high coercivity SH, ultra-high coercivity UH, extremely high coercivity EH.
