In the world of custom cooling systems, choosing the right material for components directly influences efficiency, durability, and overall system reliability. Plain Aluminum Fin Strips with O or H22 Temper is know as an optimal choice due to their superior thermal conductivity, corrosion resistance, and mechanical robustness.
Aluminum Fin Strips in Cooling Systems
Aluminum fin strips are thin, elongated pieces of aluminum designed to enhance heat exchange efficiency. These fins attach to heat sinks, condensers, evaporators, or other cooling elements. Their job is to facilitate a larger contact surface for heat dissipation between the aluminum and fluid or air, thus optimizing temperature regulation in devices like HVAC systems, automotive radiators, refrigeration units, and industrial heat exchangers.
The plain aluminum fin strip, available primarily in O temper (annealed form) and H22 temper (strain-hardened), delivers specific mechanical and thermal characteristics that favor custom design needs. By selecting between these tempering conditions, engineers can fine-tune strip flexibility, strength, and formability depending on cooling system dimension constraints and durability requirements.

Applications of Plain Aluminum Fin Strips
Plain aluminum fin strips acclimate well to diverse segments where heat exchange plays a pivotal role:
- HVAC Equipment Modules: High surface area fins allow HVAC coils to operate efficiently by maximizing heat exchange.
- Automotive Radiator Assemblies: Designed fins resist vibration and thermal cycling, ensuring long-term radiator functionality.
- Refrigeration and Freezing Units: Fin strips aid in dissipating compressors’ unwanted heat.
- Industrial Heat Exchangers: Customized sizes and tempers afford tailored performance matching specific industrial thermal requirements.
- Electronics Cooling: Employed in electronic enclosure designs to manage internal thermal profiles without adding bulk.
Each application demands materials conforming to precise standards, ensuring mechanical robustness and thermal effectiveness under operational stresses.
Aluminum Alloy and Temper Conditions
Plain aluminum fin strips commonly use the AL3003 alloy due to its balance of corrosion resistance and formability, important criteria for detailed fin manufacturing.
| Property | AL3003 Alloy |
|---|---|
| Primary Alloying Element | Manganese |
| Typical Applications | Architectural, HVAC, heat exchangers |
| Corrosion Resistance | Good |
| Workability | Excellent (especially in annealed states) |
Temper Designations Explained
- O Temper: Annealed condition; the aluminum is fully softened allowing high ductility and easy forming.
- H22 Temper: Strain-hardened and partially annealed; offers increased strength while remaining minus some workability suited for structure-critical parts.
| Temper | Description | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|
| O | Annealed, soft | 75-95 | 18-35 |
| H22 | Half-hard temper (strain-hardened) | 130-160 | 4-8 |
Choosing between these tempers depends on whether ease of bending is prioritized over mechanical strength and resilience.
Chemical Composition of AL3003 Alloy
the chemical makeup guarantees consistency in mechanical and thermal properties.
| Element | Content Range (%) |
|---|---|
| Aluminum (Al) | Balance |
| Manganese (Mn) | 1.0 - 1.5 |
| Silicon (Si) | ≤0.6 |
| Iron (Fe) | ≤0.7 |
| Copper (Cu) | ≤0.05 |
| Zinc (Zn) | ≤0.1 |
| Magnesium (Mg) | ≤0.1 |
| Others (each) | ≤0.03 |
| Others (total) | ≤0.15 |
This chemical profile maintains the alloy's thermal and mechanical performance in typical cooling environments.
