Extruded finned tubes manufactured with ASTM B163 / ASME SB163 UNS N08825 (Incoloy 825) base material are engineered for highly corrosive seawater and marine cooling environments. The metallurgical bonding between the aluminum fin and the nickel-iron-chromium alloy tube ensures excellent heat transfer efficiency while maintaining long-term resistance to chloride-induced corrosion, pitting, and stress corrosion cracking.
This product is widely used in seawater-based cooling systems where conventional stainless steels are insufficient due to aggressive chloride exposure and fluctuating salinity conditions.
ASTM B163 N08825 extruded finned tubes are widely used in:

| Base Tube Outer Diameter | 12 mm – 50 mm |
| Base Tube Wall Thickness | 1.0 mm – 5.0 mm |
| Tube Length | 1 m – 25 m (customized) |
| Fin Height | 6 mm – 17 mm |
| Fin Thickness | 0.3 mm – 0.6 mm |
| Fin Pitch | 2.0 mm – 5.0 mm |
| Fin Density | 300 – 1000 fins/m |
| Element | Content (%) |
|---|---|
| Ni (Nickel) | 38.0 – 46.0 |
| Fe (Iron) | ≥ 22.0 |
| Cr (Chromium) | 19.5 – 23.5 |
| Mo (Molybdenum) | 2.5 – 3.5 |
