Abstract
A metal composition suitable for originating a joint by means of welding with a borosilicate glass for a solar collector. The composition, expressed in weight percentage, comprises the following alloy elements: and it is such that 45.5≤(Ni+Co)≤46.5, and that (Ti+Ta+Zr)≥4×C, the remaining part being made up of iron, apart from the inevitable impurities. Additionally, a metal ring 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 thus obtained.
