I know the topic superficially: the material, i.e. sheets(!) of laminate consisting in the absolute majority of aluminium (steel and Ti were additives) were formed into tubes. This material was also used to build ski poles and masts. The problem is that the material had a tendency to "return" to its natural shape, i.e. to... spread on the weld! The material was produced by AMAG, frames for EMC were produced by Hagan - 93/94, the number of frames is unknown (if someone gave me such a gift, I would gladly accept it - it's unique; if he told me to ride it - well...)
