DIN 2.049

DIN 2.049 is a high-conductivity copper alloy, also known as Electrolytic Tough Pitch (ETP) Copper or CW004A in some standards. It is widely used for its excellent electrical and thermal conductivity.

Key Characteristics of DIN 2.049:

• Chemical Composition:

  • Copper (Cu): Minimum 99.9%

  • Oxygen content around 200 ppm (depending on process)

  • Very low impurities of metals such as lead, silver, sulfur, phosphorus, etc.

• Mechanical Properties:

  • Tensile Strength: Approximately 220 – 250 MPa

  • Elongation: Typically 20 – 40%

  • Hardness: Relatively low due to high purity copper

• Physical Properties:

  • Electrical Conductivity: ~ 100% IACS (International Annealed Copper Standard)

  • Thermal Conductivity: Very high, suitable for heat exchangers and electrical wiring

  • Density: Approximately 8.96 g/cm³

Applications:

• Electrical wiring and cables

• Electrical connectors and switches

• Transformers and coils

• Heat exchangers and plumbing applications

• General purpose electrical and thermal applications
