Advanced Copper Sheet Metal Processing
Copper sheet metal fabrication utilizes a variety of copper alloys, each selected for its distinct properties. Pure copper exhibits a light red hue that evolves to a purplish red once an oxide film forms on the surface. Renowned for its outstanding electrical conductivity—second only to silver—and exceptional thermal conductivity, which is surpassed only by gold and silver, copper also demonstrates excellent chemical stability, corrosion resistance in atmospheric, freshwater, and seawater environments, and high ductility that permits robust cold and hot pressure processing. Although its inherent low strength and hardness limit its use in structural applications, these characteristics make copper one of the most versatile and easily fabricated materials in sheet metal production. As a result, copper sheet metal components are extensively employed in a range of industries including chemical processing, aerospace, automotive, and beyond, ensuring efficient and high-precision outcomes through CNC fabrication processes.
