摘要:
A metallic eyeglass-frame, in particular its each bow has a core-to-covering structure in which high Ni-content covering is clad to the surface of a super elastic core made of Cu-Sn-Zn, Cu-Al-Zn or Cu-Al-Ni alloys in order to reduce plastic deformation during use and assure high workability in production, thereby allowing the eyeglass-frame to constantly rest stably on the wearer's facial construction with no increase in uncomfortableness and fatigue on the wearer.
