This is rather simple query for a rather convoluted issue. I'll try and stick to the simple and add the background after. The back rack found on K-75's and some K-100's is made of what material? I do not believe it is steel or other ferrous metal as it is not magnetic. Can the piece be brazed or otherwise mended? And not by epoxy, glue or such material.
Background, I previously posted a long narrative of trying to mount a top box on a K75 (https://www.k100-forum.com/t17928-back-racks-and-further-adventures). MartinW posted a really nice description with photos of how he had done just that and I tried to copy his example. Obviously I did it wrong or badly as after a rather short period the OEM back rack broke. I will attempt to post a picture of the broken piece with the fissure revealed by wire brushing at the break. So now I'm trying to repair the broken part. This is not Martin's problem, I likely did something wrong, and in addition I have another unbroken piece. But for several reasons I'm trying to restore the broken part so I can use it in another project. Hence the question of repair. Here is a photo of the broken part:
