Powering the next generation of energy technology.

In the 300 years since the discovery of copper’s extraordinary conductive properties, it has evolved to become the literal lifeline of modern society and the energy harnessing technologies that make it possible. We have played a crucial role in the evolution of copper over the past century and is poised to continue to do so in the next, as development of renewable energy sources takes century stage in the 21st century.

Developing renewable energy solutions offers unique challenges. The need for ever thinner, lighter, stronger, and smoother materials continues to push the technological edge of metals manufacturing. We welcome the challenge and is addressing it head-on through material engineering efforts in collaboration with our suppliers and OEMs. Below are a few examples of the product breakthroughs those efforts have generated, with links to technical datasheets for each.
