Characteristic
(H)
- Production cost is higher than Galva. steel wire.
- It has high straightness and non-Rotating characteristics from special heat treatment and cooling process.
- Very thin coating(EEA coating) on wire is available because of its excellent surface.
- Very easy to cut and process because of its good straightness.
- Production cost is low.
- Sensitive from exterior impact because of low young's mudulus and yield strength rate.
- It makes final products(for example : optical fiber cable) difficult for maintaining straightness and non-Rotating.
- Easy to be mutated by high load because of low young's mudulus and elongation.
