About dysprosium and terbium

Dysprosium and terbium are heavy rare earths added to NdFeB magnets so they keep their strength at high temperature. Electric vehicle motors and wind turbine generators depend on them.

Supply is concentrated and tightly controlled, so documents and licences matter as much as the material itself.

Frequently asked questions

Why are dysprosium and terbium added to magnets?

They raise the temperature at which an NdFeB magnet starts to lose its strength, which is essential in motors and generators that run hot.

How long does an export licence take?

It depends on the country and the product. We confirm the licence position at the start, so timing is clear before a contract is signed.

How is payment usually made?

By documentary letter of credit from a bank acceptable to the seller, with payment against shipping documents and the inspection certificate.
