Grade 9 titanium tube:
Grade 9(3Al-2.5V) titanium is an alloy consisting of 3% aluminum, 2.5% vanadium, and 94.5% pure titanium. This titanium alloy can be used in higher temperatures than commercially pure titanium grades 1-4, as it can be cold rolled with its excellent corrosion resistance capability its used in industrial, aerospace and sporting equipments.Final application in :
Titanium Bicycle
Titanium Wheel-chair
Titanium Golf
The Shell of Sensor in Ocean
Aerospace Applications
Our Gr.9 titanium tube are widedly used for bicyle frame,which can be bent at room temperature using standard bend techniques. It is routinely bent on a radius of three times the actual tube diameter. Moreover, thin walled tubing requires adequate support of the ID during bending. Because of the high strength and low modulus of this alloy, springbuck is about twice that of stainless steel.
The Grade 9(3Al-2.5V) Titanium Tube For Bicyle Frame alloy is characterized by-
1. Excellent resistance to seawater corrosion
2.Highest mechanical strength
3. Excellent strength to weight ratio
4.Resistant to stress corrosion cracking in chloride and sour gas environments
5. Excellent resistance to pitting, crevice and erosion corrosion
6. Good formability and weldability
7. Very low thermal expansion

Quality Control:
We use the Class A raw material to guarantee our titanium tubes quality. Shaving and boring to control the surface. NDT test (Hydrostatic, Pneumatic, E.T. U.T) to make sure each tube without crack and defect.
As a leading 3Al2.5V seamless titanium tube manufacturer, Unidus Titanium adheres to strict quality
standards to produce titanium tube. We guarantee our tube meet our customer's
