3102/H112 High Quality Microchannel Flat Aluminum Tube For Air Conditioner
Microchannel aluminum tube is mainly used for the production of heat exchangers. Due to its high corrosion-resistance & good heat conductivity, the microchannel tube is particularly well suited for the use in evaporators & condensers. The tube is required increased burst strength and better heat conductivity for an optimized product size. To meet the market requirement, we developed zinc-coated which can be supplied in the form of coils, or fixed length by non-cutting separation method.
1. Low weight
2. Good thermal and electricity conductivity
3. Good forming and bending capability
4. Good corrosion and pressure resistance
5. High recycling value
6. Narrow tolerance range
7. High surface quality
