The ASTM B163 Incoloy 825 Extruded Fin Tube with Aluminum Fin is a premium bimetallic heat transfer solution engineered for extreme environments. It combines a seamless nickel-iron-chromium alloy base tube with integrally extruded aluminum fins through a high-pressure thermal process.
This monolithic structure achieves 98% metallurgical bonding for unmatched thermal efficiency (45% higher than welded fins) and corrosion resistance in acidic, chloridic, and high-temperature applications up to 260°C (500°F).
| Element | Content (%) | Key Function |

| Nickel (Ni) | 38-46 | Acid resistance |
| Chromium (Cr) | 19.5-23.5 | Oxidation resistance |
| Iron (Fe) | ≥ 22 | Matrix stability |
| Molybdenum (Mo) | 2.5-3.5 | Pitting resistance |
| Copper (Cu) | 1.5-3.0 | Sulfuric acid resistance |
| Titanium (Ti) | 0.6-1.2 | Stabilization |
| Carbon (C) | ≤ 0.05 | Weldability |
| Property | Incoloy 825 Base | Aluminum Fin |
