In a sports racquet having a frame with a handle and a head defining an open region, a netting of a plurality of tensioned strings in an interwoven grid across the open region is formed of a metal alloy material having high elasticity, i.e., exhibiting linear elastic behavior or exhibiting stress-induced martensite-martensite transformation (super elastic or pseudo elastic) behavior. In one embodiment, the alloy described above, and a sleeve or lower durometer material, e.g., plastic. |
