Electrochemistry excellence since 1923
The secret of De Nora's success is encased in the company motto "DURANTES VINCUNT" - he who resists wins.
A simple sentence, said by Oronzio De Nora's father to congratulate his son at the end of a particularly testing exam, that has shaped the working life of Oronzio De Nora and the growth of the company.
