description PURPOSE:To obtain the titled core, by combining and brazing an operating fluid passage composed of Al alloy having a specified compsn. and fin composed of core material made of Al alloy having a specified compsn. and cover material such as Al-Sn brazer. CONSTITUTION:Operating fluid passage superior in corrosion resistance is formed with Al alloy contg. 0.03-0.2 Mg. On the other hand, fin having sacrificial effect is formed from brazing sheet composed of core material made of either of Al alloy contg. 0.1-5% Zn, 0.2-2% Mn, or further suitable quantities of Mg, Cu, Cr, Zr, etc., and Al alloy contg. 0.02-0.09% Sn, or further suitable quantities of Mg, Mn, Zn, Cu, Cr, Zr, Fe, Si, and cover material made of Al-Si or Al-Si-Mg brazer. Said operating fluid passage and fin are combined and brazed to obtain the titled core.
