Micro-Multiport Aluminum Tube for Air Conditioning Heat Exchangers1050/1100/1197/3102/3r03

Model NO.: Alloy: 1050/1100/1197/3102/3R03 Surface Treatment: Mill Finished Alloy: Alloy Trademark: RUNFAL Origin: Jiangsu Shape: Round Grade: 1000 Series Temper: O - H112 Specification: According to The Customer Request HS Code: 7608209910 Micro-multiport tube is the high-tech aluminum products under the process of hot extrusion from refined aluminum ingot and then zinc spraying for anti-corrosion.

Micro-multiport tube is the core materials of new generation parallel flow air conditioning heat exchangers. It is outstanding in enviromental-friendly, efficient, energy-saving and cost reduction and was approved vividly in automobile air conditioning system. With restriction and prohibition of the application of the traditional refrigerant, it is a trend that household and commerical air conditioning heat exchanger needs revolution.
