Abstract: There is disclosed an aluminum or aluminum alloy extruding die, which comprises Co-group alloy, Ni-group alloy, Cr-group alloy or like high temperature wear-resistant alloy coating applied by thermal spraying on a required die surface portion having been formed in the shape of a rough surface having surface roughness Rz of 5 &mgr;m or more. Preferably, after application of the alloy coating, the die is held at a temperature in the range from 500 to 800° C. for a predetermined period of time or the alloy coating surface is so roughened as to have surface roughness Rz of 10 &mgr;m or less.

Abstract: Radiator caps (266) and radiator tubes (211) are heat brazed with an ingot Z of a sacrificial material being disposed in the interior of a radiator tank main body (234), whereby, as the ingot Z of the sacrificial material is heated while being surrounded by the radiator tank main body (234), the evaporated sacrificial material is allowed to adhere to internal surfaces of the radiator tank main body (234) 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 (234) 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 (234).
