Nitinol Coiling Services

Nitinol Coils

Nitinol-based coils are unique in several ways when compared to stainless steel variations. Nitinol’s shape memory characteristics allow for flexible, complex designs that react differently to environmental stress while maintaining the desired shape of your product design.

Reinforcement Wire Coils

Today’s medical tubing manufacturers demand high-performance products from their suppliers, and CWT delivers nothing less. Our fully-equipped laboratory enables our technicians to work efficiently with OEM’s through every step of the engineering process, ensuring a fully-functional, finished product for medical catheters & diagnostic devices.
