Titanium welded tubes are processed from titanium coil and longitudinally welded by TIG process without metal filler so it guarantees the homogeneity of the welded area. Moreover, due to features such as evenness of wall thickness, each tube has the same mechanical properties as the initial coils. More equipment manufacturers prefer titanium welded tubes rather than seamless for their projects.

Application
|
1. Medical field : with very good biocompatibility with human body, medical nitinol wire can be used in medical field.
2. Eye glasses manufacturer : Low density, high toughness, high stability, biocompability with human boday, nickel titanium alloy wire is becoming more popular between eye glasses manufacturers. 3. Fishing wire: nickel titanium alloy wire now is widely used as fishign wire because of its high strenght and very good memorability and superelastic. |
