At present,the magnets used in inverter air conditioner are divided into ferrite permanent magnetic materials and high performance NdFeB permanent magnet materials.Ferrite permanent magnetic materials used in the production of low-end inverter air conditioner,high-performance NdFeB permanent magnet material is mainly used for the production of high-end inverter air conditioner.Under the energy-saving environmental protection industry policy support and technology upgrade trend,the ferrite permanent magnet material in the inverter air conditioner application will be gradually replaced by high-performance NdFeB permanent magnet material.

2016 domestic air-conditioning production are 16049 units,an increase of 2.55%,the production of inverter air conditioner are 3963 units,an increase of 2.70%.2016 inverter air conditioner in the high-end inverter air conditioner permeability is expected to be around 40%,and each high-end inverter air conditioner on average need to use high-performance NdFeB permanent magnet material is around 0.28kg,according to the estimated,2016 domestic inverter air conditioner NdFeB consumption will reach 4438 tons.Assuming 2017-2018 annual average growth of air conditioning production is 3%, high-end inverter air conditioner penetration increase 2% by per year,then 2017-2018 domestic inverter air conditioner NdFeB consumption are 4800 tons and 5179 tons,an increase of 8.15% And 7.90%.
