Was used, and A4004 was clad on both sides thereof. Each of the brazing sheets was heated in a vacuum furnace at a degree of vacuum of 10 -5 torr at 605 ° C. for 3 minutes, then left at room temperature for 2 to 3 weeks, and a strength test was conducted at each temperature. First, strength tests were performed for RT = normal temperature, RT = 150 ° C., and RT = 200 ° C., respectively. Table 2 shows the results. From the table, as the brazing sheet for the tube, the conventional product has a tensile strength at room temperature of 123 MPa.

Showed a higher tensile strength. That is, it has a strength 1.4 to 1.5 times that of the conventional product at room temperature,
The strength was 1.4 to 1.6 times at ℃ and 1.5 to 1.6 times at 200 ° C. The sample E had a Cu content of 1% in its core material.
It was present and was not suitable as a brazing sheet for heat exchangers because the core material itself melted in the vacuum furnace and the sheet surface became uneven.

It had ~ 2.2 times the strength. However, in the specimens of the brazing sheet material of 3.0 mm for the tube plate and the tank, A to C were all stronger than the conventional products, but in the specimens D and E, the brazing sheet material taken out of the vacuum furnace was used.

This is because those in Table 2 were left at room temperature for two to three weeks from the vacuum furnace, and thereby age-hardened. Next, in the case of the overaged one which was kept at 200 ° C. for 7 days after being taken out from the vacuum furnace, the strength was reduced by about 20% to 25% as compared with that in Table 2. However, in each of the above cases, the strength after aging in the conventional brazing sheet was sufficiently larger (about 1.4 times and about 1.2 times stronger).
