Product Overview:

ASTM CDA Copper Sheet refers to copper sheets that comply with the Copper Development Association (CDA) standards, including ASTM specifications for copper. These sheets are made of high-purity copper, often classified under CDA 110 (Electrolytic Tough Pitch or ETP Copper), which is known for its excellent electrical and thermal conductivity. ASTM CDA Copper Sheets are commonly used in electrical, plumbing, and industrial applications, as well as for decorative purposes. The copper’s purity and superior workability make it ideal for applications that require high-performance materials, whether for power distribution, heat exchange, or precision fabrication.

Unique Features:

ASTM CDA Copper Sheet is made from high-purity copper (CDA 110), which boasts a minimum copper content of 99.9%. This ensures exceptional electrical conductivity (100% IACS) and thermal conductivity (398 W/m·K), making it an excellent choice for electrical and heat exchange applications. The low oxygen content (0.02%) helps prevent the formation of copper oxide, improving the material’s resistance to corrosion and ensuring reliable long-term performance. ASTM CDA Copper Sheet is easy to fabricate, solder, and weld, making it suitable for a wide range of industrial, plumbing, and architectural applications. Its durability and versatility make it a staple in industries requiring high-performance copper materials.

Applications:

• Electrical Conductors: ASTM CDA Copper Sheets are ideal for manufacturing electrical conductors, including cables, connectors, and busbars. Their excellent electrical conductivity ensures minimal power loss and efficient energy transfer.
• Heat Exchangers: Due to its high thermal conductivity, ASTM CDA Copper Sheet is extensively used in heat exchangers and cooling systems. It is employed in radiators, coils, air conditioning units, and refrigeration systems to maximize heat transfer efficiency.
• Plumbing and HVAC Systems: Copper’s resistance to corrosion and high durability makes ASTM CDA Copper Sheet an excellent material for water supply pipes, fittings, and HVAC systems, ensuring long-lasting, leak-proof performance.
• Architectural Finishes: ASTM CDA Copper Sheet is used in architectural applications such as roofing, cladding, and decorative elements. Its natural aesthetic appeal and corrosion resistance make it perfect for creating beautiful, durable finishes in both residential and commercial buildings.
