摘要 |
The present invention regards a metal composition suitable for originating a joint (22) by means of welding with a borosilicate glass for a solar collector (10). The composition, expressed in weight percentage, comprises the following alloy elements Table 1 and it is such that 45.5 = (Ni+Co) = 46.5, and that (Ti+Ta+Zr) = 4 x C, the remaining part being made up of iron, apart from the inevitable impurities. The invention also regards: a metal ring (20) made of the metal composition described above and suitable for originating a metal-glass joint by means of welding; the metal-glass joint thus obtained; and the tubular solar collector (10) thus obtained. |
