Small-size ferrite square magnetic sheet is a miniature thin-plate square permanent magnetic component made of high-precision ferrite materials through fine pressing and low-temperature precise sintering. Featuring miniaturization, thin thickness, light weight and high precision, this product is a refined type of ferrite magnet, specially developed for small electronic devices, miniature electrical accessories, precision assembly parts and lightweight industrial components. It solves the problem that conventional large ferrite magnets are bulky and cannot be applied to miniaturized equipment, and fills the market gap of small-specification stable magnetic components in the precision manufacturing industry.

In terms of size and precision performance, small-size ferrite square magnetic sheets cover ultra-small specification ranges, with conventional length and width from 3mm to 30mm and thickness from 1mm to 5mm. The whole product is light and thin, with regular square outline and no dimensional deviation. Adopting micro-powder pressing and precise sintering process, the product has no deformation, warping or corner missing after forming, with flat surface and uniform thickness. The dimensional tolerance is controlled within ±0.05mm, fully meeting the zero-gap assembly requirements of miniature precision equipment. Despite its small size, the product retains stable magnetic performance, with uniform surface magnetic force and no local weak magnetism or magnetic failure.

In terms of material and environmental adaptability, small-size ferrite square magnetic sheets use high-purity fine-grain ferrite raw materials, with dense internal structure and good mechanical toughness. Compared with ordinary ferrite magnets, it is not easy to break or crack during cutting, assembly and use, with strong impact resistance and compression resistance. The product has excellent anti-oxidation and anti-corrosion performance, no rust or deterioration in dry and conventional humid environments, and has strong anti-aging ability. It can adapt to long-term stable work in small spaces with slight vibration and temperature change, with low failure rate and long service life. In addition, the product is non-toxic, environmentally friendly and pollution-free, complying with global electronic product environmental protection standards.

Small-size ferrite square magnetic sheets have extremely extensive application in precision electronics, small household appliances, communication accessories, toy parts and office supplies. In miniature electronic products such as Bluetooth headsets, smart sensors and small vibration motors, they are used for miniature magnetic positioning and functional induction; in small kitchen appliances, beauty instruments and portable electronic devices, they realize component magnetic fixing and assembly fastening; in educational toys and DIY accessory fields, they are used for small magnetic splicing and combination; in office and daily necessities, they are applied to magnetic fixing of whiteboard accessories and small adsorption parts. With the development of electronic product miniaturization and lightweight trend, small-size ferrite square magnetic sheets, as high-cost-performance miniature magnetic components, have become indispensable basic accessories in precision manufacturing and civilian industries.
