摘要： An aluminum alloy containing (in wt. %): 0.2-0.5 Fe; 0.7-1.2 Si; 1.2-1.6 Mn; up to 0.3 Mg; up to 0.5 Cu; up to 0.2 Zn; up to 0.1 Ti is used to make the fins of heat exchangers particularly car radiators. The finstock has high post braze strength and thermal conductivity, and has a sufficiently electronegative potential as to be capable of acting as a sacrificial anode for the heat exchanger tubes. By virtue of the absence of Sn, In, and Cr, these heat exchangers can be scrapped and melted for re-use.
