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.
The copper-key is a reference database containing technical information on
the most widely used copper alloys in the world. This freely accessible
website allows the user a material comparison based on their chemical
composition and more.
For any questions about the copper-key, please contact: email@example.com
The data collection and the compilation of the copper-key database have been
done to our best knowledge and in good faith. However, no guarantee is given
to its accuracy or completeness. This copper-key website is conceived only
as a source of information. For dangerous equipment (e.g. pressure vessels),
the user must refer to the national or European standards and regulations
which define the alloys and tempers permitted for such applications.
We do not accept any liability for any damage or any loss directly or
indirectly caused by or linked to the use of information contained in this
In using the copper-key these conditions are understood as being accepted.
