MultiPort Extrusions / Microchannel Aluminum Extruded Tubes 1100 / 3003 / 3102
1. Product Introduction:
The Aluminium Multi Port Extruded tubes,also called micro-channel aluminum tubes,are unique tubes developed with highly refined manufacturing quality. With their large internal surface area, they can achieve more efficient heat transfer and hence are widely used in highly effective heat exchangers.
2. The Aluminium Multi Port Extrusion (MPE) or microchannel tube is unique tube developed with the highest manufacturing quality and is characterized by the following properties:
1) Low weight
2) Excellent conductor of heat and electricity
3) High corrosion resistance
4) High recycling value
5) High surface quality
6) High pressure resistance
3. Commonly used material chemical composition
| No. | Alloy | Si | Fe | Cu | Mn | Mg | Cr | Zn | V | Ti |
| 1 | 1050 | ≤0.25 | ≤0.40 | ≤0.05 | ≤0.05 | ≤0.05 | --- | ≤0.05 | ≤0.05 | ≤0.03 |
| 2 | 1100 | ≤0.95(Si+Fe) | 0.05-0.20 | ≤0.05 | --- | --- | ≤0.10 | --- | --- | |
| 3 | 3102 | ≤0.40 | ≤0.70 | ≤0.10 | 0.05-0.40 | --- | --- | ≤0.30 | --- | ≤0.10 |
| 4 | 3003 | ≤0.15 | ≤0.15 | ≤0.01 | 0.90-1.10 | ≤0.03 | ≤0.03 | ≤0.05 | ≤0.05 | ≤0.05 |
4. Supply state and mechanical properties
| Alloy | Temper | Tensile Strength | Yield Strength | Elongation |
| 1050 | O/F/H111/H112 | ≥65MPa | ≥20MPa | ≥25% |
| 1100 | O/F/H111/H112 | ≥75MPa | ≥20MPa | ≥25% |
| 3102 | O/F/H111/H112 | ≥75MPa | ≥20MPa | ≥25% |
| 3003 | O/F/H111/H112 | ≥75MPa | ≥20MPa | ≥25% |
5. The corrosion resistance performance
Salt spray test ≥750hours
6. The pressure resistance performance
| Automobile Condensers | Household Condensers | Evaporators |
| ≥9MPa | ≥13.5 MPa | ≥3.5 MPa |
7. Beside increased global performances, an all-aluminium brazed heat exchanger using MPE will also present better corrosion resistance. MPEs are primarily used for the following applications:
1) Condensers
2) Evaporators
3) Oil coolers
4) Radiators
5) Heater cores
