Copper Key

Copper Key is published by Kupferverband e.V. and implemented by Matplus. It compares national standards (ASTM, DIN, EN, BS), materials, and designations for copper alloys. You can search by full text as well as by composition, standards, and properties.

The interface is built for materials selection and analysis: compare copper standards, then move from a comparison table into the linked dataset.

Interactive data analysis

Filter, arrange, and explore data in comparison tables, and visualize correlations through interactive graphics. Open linked datasets with one click.

Bi-directional linking

Navigate between standards, designations, and product forms through bidirectional links between datasets.

Units and languages

Switch units and languages (German and English) so the database matches how you work.

Knowledge management

Use Copper Key as a starting point for your own knowledge management. Our team can support that process.
