Introduction

Interpretation of the new standard technological innovation

As a core high-efficiency conductive material, copper-clad aluminum flat rods have improved the new national standard. The material bonding interface illustrated by a metallographic electron microscope (as shown in Figure X) shows the microstructural characteristics of the copper-aluminum diffusion layer.
