Anyone can join discussion about Titanium Pipe cantilevers, i can only recall Audio-Technica cartridges with this type of cantilever, but we're all aware of the Boron Pipe and the reason why they are better.
According to our member @simpikins5 and his inside the beryllium is the best (no wonder why the most expensive Victor has beryllium cantilever):
"There was a thread on Audiogon quite a while ago in which a former engineer from Audio-Technica was participating. He wrote a rather in depth post as to why Beryllium was the go to material for cantilevers and the panic that ensued at AT when the EPA came down with the order that it no longer be used due to the dangerous toxic dust released when machining the material. He stated that the engineering department underwent a lot of R&D to find a suitable replacement material and Boron was what they determined would be closest, however it was still a compromise. Apparently Beryllium allows for the largest frequency excursion without distortion and also permits better channel separation and signal to noise ratios. This is why it was so good."
