Ultra-thin sheet NdFeB magnetic sheet is a super-thin and flat high-precision NdFeB permanent magnet product, with a thickness usually ranging from 0.1mm to 2mm, which is processed by ultra-fine grinding, wire cutting and precision thinning processes on the basis of high-performance NdFeB magnetic materials. Compared with conventional thick magnetic sheets, this ultra-thin magnetic sheet has the characteristics of ultra-thin thickness, ultra-flat surface, light weight and high dimensional accuracy, and is a core magnetic component dedicated to ultra-thin, lightweight and miniaturized electronic and intelligent equipment. The product breaks through the thickness limitation of traditional NdFeB magnets, while retaining the high magnetic energy product and strong magnetic force characteristics of rare earth magnets, realizing high magnetic force output in ultra-thin space, and solving the problem of insufficient magnetic force of ordinary thin magnetic materials.

In terms of core performance characteristics, the ultra-thin sheet NdFeB magnetic sheet has ultra-high thickness precision, with thickness tolerance controlled within ±0.005mm, flatness up to micron level, uniform overall thickness and no warping or deformation. Under the ultra-thin size, it still maintains strong magnetic adsorption force, with far higher magnetic energy product and unit magnetic force than flexible soft magnetic sheets and ferrite thin sheets, realizing high-efficiency magnetic adsorption and induction in limited thin space. The product has stable magnetic performance, good anti-demagnetization ability, no magnetic attenuation after long-term use, and strong environmental adaptability. After ultra-thin electroplating and passivation treatment, the surface is smooth and flat, with excellent oxidation resistance and corrosion resistance, and will not be affected by humid and dusty working environments. In addition, the ultra-thin magnetic sheet has good processing flexibility, can be customized into round, square, special-shaped and other structures according to demand, and can meet the personalized customization needs of different ultra-thin equipment.

Ultra-thin sheet NdFeB magnetic sheets are mainly applied in ultra-thin lightweight electronic products, miniature intelligent equipment, precision sensing devices and other high-end fields. In the consumer electronics industry, they are the core magnetic components of ultra-thin mobile phones, tablet computers, ultra-thin Bluetooth headsets, smart watches and wearable devices, realizing the lightweight and thinning design of electronic products while ensuring the functions of wireless charging, magnetic adsorption and sensor induction. In the field of precision sensing, ultra-thin magnetic sheets are used for miniature magnetic sensors, pressure induction components and displacement detection parts, improving the sensitivity and accuracy of precision detection equipment. In the intelligent manufacturing industry, they are applied to ultra-thin equipment fixtures, micro-positioning components and thin-layer magnetic fixing parts of automated production lines, adapting to the assembly and use of ultra-thin structural parts. In addition, ultra-thin sheet NdFeB magnetic sheets are also widely used in medical portable equipment, aerospace ultra-thin precision instruments, automobile thin electronic components and high-end packaging magnetic accessories. With the continuous thinning and lightweight development of global intelligent electronic products, the market demand for high-precision ultra-thin NdFeB magnetic sheets is growing rapidly, with broad development prospects.
