Our Expression of thanks is dedicated to Mr Dipl.-Ing. Hanns-Joachim Fischer († 2005), Brühl, who did a great contribution to the copperkey. He brought his professional experiences together into a compilation of all standard specifications of non-ferrous metal products - and so the Copper-Key was born.

Expression of thanks to Mr. Dipl.-Ing. Fischer
