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

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.Chemical CompositionNoAlloySiFeCuMnMgCrZnVTi011050≤ 0.25≤ 0.40≤ 0.05≤ 0.05≤ 0.05---≤ 0.05≤ 0.05≤ 0.03021100≤ 0.95(Si+Fe)0.05-0.20≤ 0.05------≤ 0.10------031197≤ 0.15≤ 0.200.40-0.550.10-0.20≤ 0.03≤ 0.05≤ 0.05≤ 0.05≤ 0.05043102≤ 0.40≤ 0.70≤ 0.100.05-0.40------≤ 0.30---≤ 0.10053R03≤ 0.15≤ 0.15≤ 0.010.90-1.10≤ 0.03≤ 0.03≤ 0.05≤ 0.05≤ 0.05
