About Dean Titanium BikesDEAN Bikes use only the finest titanium available: - U.S. made 3/2.5 seamless, cold worked, stress relieved - grade 9 titanium. - This radially butted 3/2.5 CWSR titanium tubing is CNC machine to precision tolerances. - The 6/4 seamless titanium is precision machine butted by Reynolds.
DEAN Titanium consists of 3% aluminum, 2.5% vanadium and 94.5% pure titanium. Exclusive to our titanium is the "R" grade processing. This allows for radially aligned crystals. This dramatically increases strength and durability. Titanium possess a minimum yield strength of 105 ksi and a minimum UTS (ulitmate tensile strength) of 125 ksi. It has a annealed elongation of 15-20% and a cold-worked ductility of 10%. Titanium has a fatigue strength-to-weight ratio roughly twice that of 4130 cromoly steel. As well as it has superior resiliency and corrosion resistance.
