Silver Plated Copper Clad Aluminum Description

Ulbrich Lite Weight CCA & SPCCA is a lighter alternative to pure copper with an approximate weight savings of 70% to copper while retaining desirable electrical properties. This material is ideal for aerospace, military, satellite and other weight conscious applications. To demonstrate the weight saving potential, a graph is included below showing the difference in weight between a pure copper round wire and that same length and size wire made of copper clad aluminum.
