Diehl Metal Applications recommends special alloys that are the perfect choice for various application areas:

Precision strip for connectors:

These alloys meet the highest requirements on heat resistance and elastic properties. They reveal an adequate electrical conductivity.

Strip for roll-bonding:

For this application composite materials are recommended that consist of a base material of low metal value and a functional material as coating.
The  precision strip are used in connectors, electrical contacts and coins.

Strip for cups, discs, keys, coins and medals:

Cups or discs require good deep-drawing properties and a texture-free structure (avoidance of earing). Our prematerial for coins and medals allows excellent stamping, embossing, milling and polishing.
