摘要
The present invention relates to a heat exchanger assembly having a plurality of heat exchange fluid passageways formed from a modified copper-zinc alloy. The copper-zinc alloy contains from about 21% to about 39% zinc, from about 1% to about 5% nickel, from about 0.02% to about 1% arsenic and the balance essentially copper. In a preferred embodiment, the copper-zinc alloy consists essentially of from about 25% to about 35% zinc, from about 2.5% to about 3.5% nickel, from about 0.03% to about 0.06% arsenic and the balance essentially copper. The heat exchanger assemblies of the present invention have particular utility as motor vehicle radiators.
