ASTM A179 Carbon Steel Fin Tube Extruded Type With Al1060 For Air Cooled Chiller
Product Overview
The extruded fin tube is manufactured by inserting a carbon steel seamless tube (ASTM A179) into a pure aluminium Al1060 sleeve, followed by a high-pressure extrusion process that forms integral fins from the aluminium sleeve. This method ensures a perfect metallurgical bond between fins and tube, eliminating air gaps and providing maximum thermal conductivity.
| Element | C | Mn | P (max) | S (max) |
|---|---|---|---|---|
| Content (%) | ≤ 0.06 | 0.27–0.63 | ≤ 0.035 | ≤ 0.035 |
| Property | Requirement |
|---|---|
| Tensile Strength | ≥ 325 MPa |
| Yield Strength | ≥ 180 MPa |
| Elongation | ≥ 35% |
| Hardness | ≤ 72 HRB |
Advantages
Superior heat transfer efficiency due to firm aluminium-to-steel bonding.
Lightweight and high conductivity of Al1060 provides excellent thermal performance.
Corrosion protection → Aluminium fins shield the carbon steel tube from environmental damage.
Durability → Withstands vibration, thermal cycling, and long service periods.
Cost-effective → Combines low-cost carbon steel tubing with high-conductivity aluminium fins
