Unique Features:

EM 1978 Copper Sheet stands out due to its high-purity oxygen-free copper (Cu-OFE) composition, which ensures exceptional conductivity—both electrical (101% IACS) and thermal (398 W/m·K).

The low oxygen content (0.001%) makes it resistant to embrittlement and oxidation, enhancing its durability and making it ideal for critical applications where performance is paramount.

In addition to its impressive electrical and thermal conductivity, the copper sheet offers excellent formability, allowing it to be easily processed, soldado, and fabricated into various shapes and sizes.

This makes EN 1978 Copper Sheet highly versatile for a wide range of industrial, electrical, and decorative uses.
