If the material is failing, it is due to those that chose it and or provided the specs for the material!!!
Whilst that can often be the case, i can attest to the fact that even some simple well understood materials ( Steel, Aluminium) , can often have dramatically different properties even when closely specified , Tested, and QC inspected, depending on supply source.. The real art of design is to select a material that has a wide range of functionality for the application. One of the big obstacles to quality and longevity is always cost. Often when something is copied, the exact material specification cannot be determined and a "similar" ( or cheaper) material is substituted.
