Ferrite Magnet Price Trends
Updated 3rd May 2023
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 April 2023, the price has fallen back to 9,000 CNY/MT. This is the lowest price since March 2021.
Ferrite Oxide prices are far less volatile, peaking in May 2022 at 4,050 CNY/MT. Prices reached a low of 3,520 in September 2022 and have since risen steadily to 3,670.
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.
