1. What is ASTM A269 TP304 Extruded Finned Tube with Aluminum 1060?

The ASTM A269 TP304 Extruded Finned Tube with Aluminum 1060 is a premium heat transfer solution designed for corrosive and high-purity applications. It combines a seamless austenitic stainless steel base tube (ASTM A269 TP304, 18% Cr, 8% Ni) with Aluminum 1060 fins (99.6% pure aluminum) through a precision extrusion process. The fins are mechanically bonded to the tube surface under controlled conditions, ensuring a seamless, gap-free interface. This hybrid design leverages the corrosion resistance of TP304 stainless steel in acidic/chloride environments and the ultra-high thermal conductivity of Aluminum 1060, making it ideal for industries requiring hygiene, durability, and rapid heat transfer.

2. Chemical & Mechanical Properties

Chemical Properties

Component	Chemical Composition	Key Features
ASTM A269 TP304 Base Tube	• Cr: 18–20%, Ni: 8–10.5%, C: ≤0.08%, Mn: ≤2.0%, Fe: Balance.	• Resists pitting, crevice corrosion, and oxidizing acids. • Passivation-ready for hygienic applications.
Aluminum 1060 Fins	• Al: 99.6% min, Fe+Si: ≤0.40%, Cu: ≤0.05%.	• Exceptional thermal conductivity (235 W/m·K). • Non-reactive in neutral/alkaline environments.
Synergy	• Electrically insulated bonding prevents galvanic corrosion between steel and aluminum.	• Ideal for systems with thermal cycling and humidity.

Mechanical Properties

Component	Mechanical Performance	Key Features
ASTM A269 TP304 Base Tube	• Tensile Strength: 515–860 MPa • Yield Strength: 205 MPa (min) • Hardness: 70–90 HRB.	• High-pressure tolerance (up to 30 MPa). • Maintains ductility at cryogenic temperatures.
Aluminum 1060 Fins	• Tensile Strength: 70–110 MPa • Elongation: 15–25% • Hardness: 23 HB.	• Lightweight for reduced structural load. • Easy to clean and maintain.
Bond Integrity	• Shear Strength: ≥50 MPa at fin-tube interface. • Thermal Cycling: Stable under ΔT up to 300°C.	• Zero fin detachment under vibration.

3. Key Applications

· Pharmaceutical & Biotechnology: Sterilizable heat exchangers for clean-in-place (CIP) systems.

· Food & Beverage: Hygienic pasteurizers, chillers, and steam heating systems (FDA/EHEDG compliant).

· Chemical Processing: Acid-resistant condensers and reactors.

· HVAC & Refrigeration: Energy-efficient air coolers and heat pumps.

· Marine Engineering: Corrosion-resistant cooling systems for seawater desalination.

4.Why Choose ASTM A269 TP304 + Aluminum 1060 Finned Tubes?
