Titanium Hollow Bar

titanium hollow barNorth Steel Co, product range of titanium hollow bars includes a wide range of titanium and titanium alloys with a wide range of diameters from 30mm to 280mm with tolerances assured to length of x2.5 of Outside Diameter.

Hollow bars are tube forms which are engineering through the engineering of a titanium rod or bar. Hollow bars are used in applications where the dimensions of a tube cannot be achieved through typical welding and extrusion based approaches. A key feature in hollow bars is the ability to machine the more with accuracy and depth.

North Steel Co, supplies titanium hollow bar across a wide range of industries and applications and are able to offer one of the widest range of titanium bar diameters at the longest length.
