DyFe Price Trend

Dysprosium is a heavy rare earth element with metallic silver luster. Dysprosium is never found in nature as the simple substance but found in various minerals like xenotime. Almost all of Dysprosium refined in China, then primarily used to the activator of phosphor, giant magnetostrictive TbDyFe Terfenol-D, and magneto-optical memory material. Dysprosium can significantly enhance intrinsic coercivity Hcj of sintered Neodymium magnet. Dysprosium is generally used in the form of Ferro Dysprosium alloy due to the price factor. DyFe alloy is an acronym for Dysprosium Iron alloy. Nominal content of Dy and Fe in Dy alloy is 80% and 20%, respectively. DyFe price has considerable influence on the cost of high coercivity sintered Neodymium magnet. In order to ensure rational use of rare earth resource, supply chain stability, and cost advantage, either downstream magnet consumers or manufacturers have been trying to get rid of heavy rare earth elements Dysprosium and Terbium, thus launched many Dy-free or Dy-less solution, such as grain refining technology and latest grain boundary diffusion (GBD) technology.
