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.

Surface Condition • Black oxide
• Light oxide (varies from golden yellow to brown)
Packaging Options • Spooled: wire wound evenly on spools, without breaks or tangles
• Fixed-length (cut-to-length according to customer length specification, shear-cut or EDM-cut)
• Custom packaging solutions
