Premium CU-ETP Oxygen-Free Copper Sheet Thickness 0.5 – 80.0mm with Excellent Thermal Performance

The Premium CU-ETP Oxygen-Free Copper Sheet represents one of the highest-quality copper materials available for industrial, electrical, and thermal-management applications. Manufactured with exceptional purity and engineered for maximum conductivity, CU-ETP copper (also known as C11000 copper) is widely used in industries where efficient heat transfer and electrical performance are essential. With available thicknesses ranging from 0.5 mm to 80.0 mm, these copper sheets offer outstanding flexibility for precision manufacturing, CNC machining, stamping, and custom-fabricated parts.

Combining high electrical conductivity, low oxygen content, and excellent thermal dissipation, CU-ETP copper sheets are the first choice for demanding environments such as power generation, electronics, automotive systems, and renewable-energy technologies.

1. Product Overview

The Premium CU-ETP Oxygen-Free Copper Sheet is produced using advanced refining technologies that reduce oxygen levels to below 0.04%. This minimizes hydrogen embrittlement and ensures superb performance under conditions involving heat, high current, or corrosive environments. CU-ETP copper is well-known for its:

• Conductivity above 101% IACS

• Superior thermal transfer efficiency

• Excellent ductility and formability

• Smooth surface finish for precision machining

• Reliable oxidation and corrosion resistance

These features make CU-ETP copper sheets ideal for both structural and functional components in high-tech applications.

2. Key Features and Benefits

✔ Exceptional Electrical Conductivity

CU-ETP copper is widely regarded as the preferred material for electrical applications. With conductivity exceeding 101% IACS, it ensures low energy loss and stable performance even under high-intensity loads.

✔ Outstanding Thermal Performance

Engineered for high thermal transfer, CU-ETP sheets effectively dissipate heat, making them suitable for heat sinks, cooling plates, power-distribution components, and thermal shielding structures.

✔ High Purity and Extremely Low Oxygen Content

With oxygen content typically below 0.04%, CU-ETP copper minimizes the risk of embrittlement, ensuring mechanical stability and long product life in high-temperature or vacuum environments.

✔ Wide Thickness Range (0.5–80.0 mm)

The product’s broad thickness range allows versatility in manufacturing, from thin electronic components to heavy industrial plates.

✔ Excellent Formability and Machinability

CU-ETP copper offers easy shaping, bending, stamping, and CNC machining without cracking or performance degradation.

✔ Superior Corrosion Resistance

The natural corrosion resistance of high-purity copper makes it suitable for harsh environments, including marine, industrial, and high-moisture conditions.
