Dysprosium Metal Dy CAS 7429-91-6 For Additive Of NdFeB Magnets
Name: Dysprosium metal, distillation Dysprosium Molecular formula: Dy
CAS: 7429-91-6 Molecular weight: 162.50
Description: Dysprosium can be made into various forms: Dysprosium Foil, Dysprosium block, Dysprosium sheet, Dysprosium powder, Dysprosium sputtering target. The abundance of Dysprosium in the earth's crust is 6 ppm, which is lower than that of Yttrium in heavy rare earth. It is a relatively rich heavy rare earth element, which provides a good resource base for its application. Dysprosium is a soft metal with glossy ductility. It is easy to be corroded by air at high temperature, but stable at room temperature. Work slowly with water.

Package: Under Argon atmosphere or vacuum packaging, 25kg or 50kg per bag, also provide small package: 100g, 500g, 1kg, 5kg and other small packaging.
Use: It is mainly used as an additive of NdFeB permanent magnet, the coercive force of the magnet can be increased by adding about 2-3% Dysprosium. Dysprosium is a necessary metal raw material for the preparation of TbDyFe (Terfenol) alloy, which can realize some precise mechanical movements. Dysprosium metal can also be used as magneto-optical storage material with high recording speed and reading sensitivity.
