摘要

The League of set of fins of high conductivity, method of production and resulting product. The present invention relates to an alloy of a set of fins of high conductivity which is for heat exchangers of welded aluminum.Set of vanes comprises an aluminium alloy comprised of approximately 0.7 - 1.2%; about 1.9 - 2.4% Fe, about 0.6 - 1.0% of Mn; up to about 0.5% Mg, up to about 2.5% Zn; up to about 0.10% Ti, and even some 0.05% in; with the remainder comprising Al and the impurez The tolerable.Method for production of a set of fins from the aluminum alloy lingotar precedent being the league as a strip with a thickness of about 2 to 10 mm at an average rate of cooling above about 300 198 C / S. and then the cold blade with multiple passes to get us I 'm is one or more partial recozimentos intermediaries to a temperature of about 300 - 450 198 C.It is also described a flap made from the set of fins previously said. It is also described a heat exchanger of welded aluminum having cooling fins made of the number of fins previously said.
