Abstract

A high-conductivity finstock alloy is for brazed aluminum heat exchangers. The finstock comprises an aluminum alloy comprised of between about 0.7-1.2 % Si; about 1.9-2.4 % Fe; about 0.6-1.0 % Mn; up to about 0.5 % Mg; up to about 2.5 % Zn; up to about 0.10 % Ti; and up to about 0.05 % In; with the remainder comprising Al and tolerable impurities. A method of manufacturing finstock from the foregoing aluminum alloy comprises continuously casting the alloy as a strip with a thickness of about 2-10 mm at an average cooling rate above about 300 °C/sec. And then multiple pass cold rolling the strip using one or more intermediate partial anneals at a temperature of about 300-450 °C. A fin made from the foregoing finstock is also disclosed. A brazed aluminum heat exchanger having cooling fins made from the foregoing finstock is also disclosed.
