2. Material Selection – Aluminium Alloy 6061-T6
Sinupower selects high-grade aluminium alloy 6061-T6 and 6063-T5 for the Maximum Thermal Dissipation D-Type Condenser Header Pipes based on verified material properties:
167 Thermal Conductivity (W/m·K) — verified material property
2.70 Density (g/cm³) — 40% lighter than copper (8.96 g/cm³)
520+ Salt Spray Resistance (hours, ASTM B117) — standard test method
Data Note: Thermal conductivity, density, and corrosion resistance figures are published material properties of 6061-T6 aluminium alloy. Actual component performance depends on system design, operating conditions, and integration with other components. Sinupower recommends customer-specific validation.
