- On demand we can deliver strips or finished components.

 

1. PROPERTIES
2. APPLICATIONS.

Very convenient for equipment for high frequencies and in general for all elements put under high dynamic stresses with high resistance to fatigue, can also be used extensively for test instrucments of PCB, and sports equipment.
