Aluminum foil for auto radiator 8011 and 1060 are widely used for making radiator, it can reduce the weight of car radiator by about 30%. The aluminum foil radiator are applied in machinery, automobiles, wind power generation, construction machinery, air compressors, railway locomotives, household appliances and other industries due to their beautiful appearance, light weight, good heat dissipation performance and good energy saving effect.
At present, the core material of my country’s automobile radiator is mainly composed of composite brazing aluminum foil, and the composite material is composed of aluminum alloy covered with aluminum silicon type brazing material on both sides. The working environment of automotive radiator aluminum foil is relatively harsh, and it requires good corrosion resistance and collapse resistance. Because in recent years, in order to meet the needs of lightweight cars, miniaturization of parts, and lower material costs, the thickness of aluminum foil has been decreasing. The thickness of the current market can only be 0.08mm, and the thickness of less than 0.08mm cannot meet the collapse resistance.
The aluminum foil for auto radiator has high strength, good collapse resistance and heat exchange ability, and can have good sag resistance during high temperature brazing. The aluminum foil for automobile radiator, the core layer is composed of silicon, iron, copper, manganese, chromium, titanium and aluminum, and the mass ratio of each component of the core layer is: silicon 0.2～0.45%, iron 0.31～0.40%, copper 0.30 ～0.40%, manganese 1.0～1.8%, chromium 0.005～0.035%, titanium 0.12～0.20%, the rest is aluminum.
