Abstract
Radiator caps ( ) and radiator tubes ( ) are heat brazed with an ingot Z of a sacrificial material being disposed in the interior of a radiator tank main body ( ), whereby, as the ingot Z of the sacrificial material is heated while being surrounded by the radiator tank main body ( ), the evaporated sacrificial material is allowed to adhere to internal surfaces of the radiator tank main body ( ) relatively uniformly, the sacrificial material so adhering to the internal surfaces being then allowed to be radiated into aluminum constituting the radiator tank main body ( ) to thereby form an alloy layer (a corrosion preventing layer) containing therein the sacrificial material heavily on the internal surface of the radiator tank main body ( ).
