Unique Features:

ASTM B370 Copper Coil offers a remarkable combination of excellent electrical and thermal conductivity due to its high purity, with a conductivity rating of 100% IACS (International Annealed Copper Standard). This makes it the preferred choice for electrical wiring, connectors, and other electrical components. The material’s low oxygen content (0.02% max) prevents the formation of copper oxide, ensuring stable conductivity even in challenging environments. ASTM B370 also exhibits outstanding formability, allowing it to be easily bent and shaped without compromising its performance. Its corrosion resistance ensures that it can be used in a variety of environments, from indoor electrical applications to outdoor plumbing and HVAC systems.

Applications:

• Electrical Wiring: Widely used in power cables, electrical wiring, and connectors due to its superior electrical conductivity and minimal oxidation.
• Telecommunications: Used in the manufacturing of communication cables and connectors that require high reliability and consistent performance.
• HVAC Systems: Employed in heat exchangers, cooling systems, and refrigeration components, where excellent thermal conductivity is necessary for efficient heat transfer.
• Automotive Components: Commonly used in automotive electronics, sensors, and other critical components requiring high conductivity and corrosion resistance.
• Plumbing: Ideal for plumbing systems where copper’s resistance to corrosion and bacterial growth is essential, particularly in drinking water systems.

Frequently Asked Questions (FAQ):

1. What is the difference between ASTM B370 Copper Coil and ASTM B152 Copper Coil?
   • Both are high-quality copper products, but ASTM B370 is made from oxygen-free copper (C10200) with a slightly higher purity (99.95%), making it ideal for applications that require higher conductivity and minimal oxidation. ASTM B152 is typically used for general electrical and industrial applications but is less pure than B370.
2. Can ASTM B370 Copper Coil be used for high-temperature applications?
   • Yes, ASTM B370 Copper Coil can withstand high temperatures and is commonly used in applications such as heat exchangers and electrical systems that operate under high temperatures. However, copper can lose its strength at extremely high temperatures, so proper design considerations should be made.
3. Is ASTM B370 Copper Coil suitable for outdoor applications?
   • Yes, it is suitable for outdoor applications, particularly in HVAC and plumbing systems, as it is highly resistant to corrosion and oxidation. However, the application should be in environments where exposure to extreme weather conditions or highly corrosive agents is minimal.
4. What are the typical surface finishes for ASTM B370 Copper Coil?
   • The typical surface finishes for ASTM B370 Copper Coil are mill finish and bright annealed, providing a clean and smooth surface that is ideal for welding and other manufacturing processes.
5. What is the maximum thickness available for ASTM B370 Copper Coil?
   • ASTM B370 Copper Coil is available in a wide range of thicknesses from 0.2mm up to 10mm, depending on the specific application and requirements.
6. How is ASTM B370 Copper Coil packaged for shipment?
   • ASTM B370 Copper Coil is carefully wrapped in protective film to prevent surface damage. For larger orders, the coils are packed on wooden pallets or crates for safe transport. Custom packaging can be arranged upon request.
