We’ve been leaders in copper machining since the first power semiconductor devices.

These devices had to be made from nearly pure copper – what is known today as Oxygen-Free High-Conductivity Copper (OFHC). Dawson Shanahan was commissioned because this was a notoriously difficult material to machine and we succeeded in machining the OFHC.


Today, we continue to provide innovative solutions for electronics and power generation. We not only manufacture but also assemble, test and deliver ready-to-install solutions.


We work to the highest ISO quality standards, partnering with your design and production teams to select the best materials, and maximise component performance and operating life at optimum cost. Additionally, we can manufacture, assemble and test full systems or sub-systems, delivering a complete, ready to install solution for OEMs or end users.
