Rare earth permanent magnets, especially high-performance neodymium iron boron (NdFeB) and samarium cobalt (SmCo) permanent magnets, play a vital role in modern industry.
High performance corrosion resistant magnetized diversity bonded magnets are an innovative product that combines advanced material science and precision manufacturing technology, designed to achieve high performance in harsh environments.
In order to achieve a balance between high magnetism and corrosion resistance, researchers and engineers have conducted in-depth explorations from multiple aspects such as material design, surface treatment and preparation process.
The application of sintered NdFeB magnets in micro motors is important because it provides high-performance magnetic properties, excellent physical properties, miniaturization and lightweight advantages
MIM technology has advantages that conventional powder metallurgy, machining and precision casting methods cannot match
The basic process is: various fine metal powders (generally less than 20um) are mixed with a preset binder in a certain proportion to make a feed with rheological properties
