を延ばすことができる等の利点を有する。As described above, the present invention is made by crafting a core material of JIS standard A3003 material with a brazing material of JIS standard A4343 material, and an aluminum radiator tube that is brazed with a fin made of JIS standard A3003 with zinc added. In this case, core material of JIS standard A3003 material and JIS standard A4 material
Since an aluminum alloy that is stronger than JIS Standard A3003 material and has a higher melting point than JIS Standard A4343 material is inserted between the fillet of JIS Standard A4343 material and the brazing material of JIS Standard A4343 material, brazing is performed using a fillet made of JIS Standard A4343 material that is formed later. This eliminates the problem of cracks or intergranular corrosion in the radiator tube, and has the advantage of extending the life of the radiator.
