摘要 |
There is disclosed a sacrificial corrosion-protective aluminum alloy for heat exchangers which contains Zn more than 4.0 wt% but 15.0 wt% or less, 0.1 to 3.0 wt% of Fe, and 0.2 to 3.0 wt% of Ni, with the balance being made of aluminum and unavoidable impurities. There is also disclosed an aluminum alloy composite material in which the said aluminum alloy is used as the sacrificial material and a heat exchanger using the aluminum alloy composite material. According to the aluminum alloy composite material, it is possible to prevent erosion of heat-exchanger tubes when refrigerant in tube is strongly alkaline and is flowing at a high flow rate. |
