Ferrite Magnet Price Trends
By Paul Fears | 21 July 2021

The Strontium Ferrite (SrFe12O19) permanent magnet (also known as a ceramic magnet) is the most commonly used magnet material. Each Ferrite Magnet consists of approximately 90% iron oxide and 10% strontium carbonate.
In June 2021, the price of Strontium Carbonate rose sharply, peaking at 22,250 CNY/MT in July 2021. By January 2023, the price has fallen back to 9,500 CNY/MT, the first time the price has dropped below 10,000 since April 2021.
Ferrite Oxide prices peaked in May 2022 at 4,050 CNY/MT. Prices have since fallen, levelling out at around 3,580.
Strontium Ferrite Magnet Pricing
The Strontium Ferrite (SrFe12O19) magnet features in a diverse range of applications including switches, electric motors, telecommunications, and electronics. Strontium hexaferrite’s hard magnet material has a high coercivity due to its magnetocrystalline anisotropy. The material’s resistance to corrosion and demagnetisation, and the ability to operate in temperatures up to 300°C, makes it ideal for a diverse range of applications.
Strontium is derived from Celestitie with 50% [data relates to 2014] of the global supply originating in China. Production issues have restricted the mining of the ore, resulting in a global shortage. Other producers in countries such as Spain (26%) and Mexico (20%) have also experienced production issues due to the COVID-19 pandemic.
Ferric Oxide, used in the manufacture of Ferrite Magnets, l is sourced from iron scale peeling off steel during the manufacturing process. Such iron scale is reprocessed to meet the right specification for ferrite magnets. As China is both the largest global source of ferrite oxide and ferrite magnets (60% of global production), changes in policy such as reduced steel manufacturing impact the availability and thus price of the ferrite oxide.
