Dysprosium Iron Alloy Price Trend

Dysprosium iron alloy, commonly referred to as DyFe alloy, is composed of dysprosium and iron. In the production of high-coercivity Neodymium magnets, dysprosium is typically introduced in the form of dysprosium iron alloy rather than pure dysprosium metal due to cost considerations. The nominal contents of dysprosium and iron in DyFe alloy are 80% and 20%, respectively.

The intrinsic coercivity of Neodymium (NdFeB) magnets decreases as temperature rises. Dysprosium can partially replace neodymium in the main magnetic phase to improve intrinsic coercivity and resistance to demagnetization at elevated temperatures or under strong reverse magnetic fields. However, dysprosium addition can also reduce remanence and increase raw material costs.

As a result, the price of dysprosium iron alloy is an important cost factor for high-coercivity Neodymium magnet grades. Its influence depends on the amount of dysprosium required, the magnet grade, and the production route used to introduce dysprosium into the magnet.

Reducing Dysprosium Use and Dy-Free Magnets

Concerns related to the price and supply of dysprosium iron alloy, together with environmental and social responsibility considerations, have encouraged the development of production routes that use dysprosium more efficiently or avoid it altogether.

Grain boundary diffusion provides a more efficient way to use dysprosium or terbium than conventional alloying. It can reduce the overall amount required to achieve a given level of coercivity, helping lower material costs and dependence on heavy rare earth elements.

A further step is the development of Dy-free Neodymium magnets as an HRE-free solution. In addition to reducing dependence on dysprosium iron alloy, this route can reduce exposure to export licensing requirements that apply to Dy-containing Neodymium magnet materials. Actual export compliance still needs to be reviewed based on material composition, destination, end use, and current regulatory requirements. Their performance depends on composition design, grain refinement, grain boundary control, and manufacturing processes.

Dy-less and Dy-free routes represent different levels of dependence on dysprosium iron alloy. The appropriate choice still depends on the required coercivity, operating temperature, demagnetizing conditions, magnet dimensions, and overall magnetic performance.
