Nitinol Wire Rope
Nitinol WIRE ROPE
Nitinol Rope
Nitinol rope is formed by wrapping several filaments of nitinol wire together. They exhibit the super-elastic property of nitinol material, while embodying the excellent flexibility, controllability, and miniaturization of stainless steel wire ropes.
