Product Introduction
Aluminum microchannel tube (also called aluminum flat tube or multi-port extrusion) delivers 30 % higher heat-transfer efficiency versus traditional round pipe. 3003-modified alloy + high-frequency welding guarantees zero leak under 12 MPa burst pressure—ideal for EV battery cooling, HVAC-R condenser, and charge-air intercooler.

FAQ
Q1: Microchannel aluminum tube vs. round tube heat transfer difference?
A1: 30 % higher HTC (heat-transfer coefficient) thanks to hydraulic diameter <0.5 mm and interrupted fin design.
Q2: Can you supply clad aluminum microchannel tube for CAB brazing?
A2: Yes, 4343/3003/7072 tri-layer clad, 4 % Si layer, melting range 607–613 °C.
Q3: Minimum bending radius?
A3: 1.5×tube height with mandrel, no crack at 10× magnification.
