Pretty accurate assumption. Although you have to be careful indicating that something which is lighter will be softer, see the comments about titanium alloys wrt stainless steel above, a similar situation applies with magnesium alloys wrt aluminium alloys. There is a bit more to it because manufacturing requirements, types of loadings and other design constraints prevent the same materials being used for all applications. But yes, the fixed stuff would wear a lot faster if the non fixed gear had similar mechanical properties. |
