Titanium is where we started back in 1991 and to this day all Titus titanium frames are still built in our Tempe facility.
Through the years our cutting edge design and tube fabrications as well as our meticulous attention to detail is what has positioned
Titus as the one of the leading titanium frame companies in the world.
We use only U.S. aerospace-grade; 3al/2.5v titanium tubing that is both butted and shaped in our own facility. Our state-of-the-art weld
fixtures insure perfect frame alignment after welding and eliminate un-needed cold-working used by our competitors.
A Bicycle frame represents an ideal application for titanium tubing. Titanium alloys offer the greatest combination of physical,
mechanical and chemical properties to yield a frame with the best combination of durability, ride quality, stiffness and weight.
Titanium is extremely resistant to corrosion. This property has lead to titanium’s use as storage containers for caustic materials in the
chemical industry. For you as a cyclist, this means that all the salty roads, messy mud and stream crossing you ride over or through will not rust
your bicycle, ever. Titanium frames are lifetime frames.
The density of titanium is nearly twice that of aluminum (though aluminum is the weaker of the two metals), but only 56% the density of
steel. The stiffness of titanium is also about half that of steel. It therefore follows that the stiffness-to-weight ratio of the two metals is
nearly the same. In English this means that titanium is nearly as strong as, but is lighter than steel.
Elongation numbers of a metal tell us how much a material will bend before it breaks. Titanium’s 20 – 30 % elongation beats out steel’s
10 – 15% and aluminum’s 6 – 12%. The lower the elongation number, the more brittle and breakable a material is. The higher the elongation number,
the stronger the material is. So, the same amount of titanium stretched out into a tube will wear less than the same amount of steel or aluminum
stretched out to the same size tube. Carbon fiber does not stretch; it must be molded into form.
Fatigue strength is another measurement taken to compare metals. Fatigue is the result of accumulated wear from repetitive cycles of force.
Aluminum is notorious for having such a low fatigue strength that there is no threshold, no level of strain below which the metal will not fail. This
means that the strain on a bike frame from each pedal stroke contributes to the frame’s fatigue failure. The effect can be delayed by over sizing the
tubes to add stiffness, but the tubes end up being very thin walled and give a bone-jarring ride. In comparison, titanium has a threshold below which
it will never fail, no matter how many times the cycles of force are applied. Yes, this means that titanium will never fatigue and never fail as long
as the load it bears is below a certain level (which the stress we put on it riding is). |
