According to different production processes, neodymium iron boron permanent magnet materials can be divided into three types: sintering, bonding, and hot pressing. Today, we will talk about the competition and advantages among these three types of neodymium iron boron.

Competition and advantages among the three major neodymium iron boron

Sintered neodymium iron boron, bonded neodymium iron boron, and hot pressed neodymium iron boron can have common application areas, mainly manifested in micro electric motor products, so there is competition. However, their subtle absolute advantages also make them occupy their own unique applications.

Comparison of Three Major Neodymium Iron Borons

Sintered neodymium iron boron flake and tile shaped products (neodymium iron boron strong magnetic tiles) are easy to manufacture and process, thus having batch and cost effects; Bonded neodymium iron boron is skilled in the manufacturing of complex shaped (irregular) products, which can be said to be unique. Hot pressed neodymium iron boron is more suitable for the manufacturing of small-sized and high magnetic requirements radiation ring magnets, which can be called precise design.

The cost and performance of hot pressed neodymium iron boron are superior to sintered neodymium iron boron, and it is expected to replace sintered neodymium iron boron in multiple fields such as automotive EPS, wind power motors, and air conditioning compressors. However, the current forming process of hot pressed neodymium iron boron is limited and can only be made into a ring shape, greatly limiting its application range.

Purchase magnets

From a procurement perspective, how to make a choice between sintered neodymium iron boron, bonded neodymium iron boron, and hot pressed neodymium iron boron?

Beyond conventional circumstances, such procurement demands should incorporate multiple factors——

Mainly considering or focusing on the sales price of magnets, their corrosion resistance and high-temperature resistance performance; We may even explore factors such as raw material costs, productivity, and yield for comprehensive evaluation.
