Titanium Bicycle

　　　　　　　　　　　　　　　　　character
　　The use of titanium was largely spurred on by the aerospace industry after WWII, which sought stronger materials than the aluminumalloys they were using, while maintaining the stringent requirements for weight. Titanium is extremely difficult to process, which accounts for its high price.
　　Like most metals, titanium is combined with alloying elements to make alloys of titanium that are stronger and have other useful properties. The two most common for aerospace applications are Ti 6-4 (6% Aluminum, 4% Vanadium, 90% Titanium), and Ti 3-2.5 (3% Aluminum, 2.5% Vanadium, and 94.5% Titanium). Ti 3-2.5 was created specifically to make high

strength tubing, while T- 6-4 was created for structural components in airframe applications. Titanium is 43% lighter than steel, but its tensile strength is higher than that of steel. We use high-quality seamless titanium alloy tube(Ti3-2.5v)for a strength-to-weight ration 28.4% higher than chromoly. Titanium is also one of the materials that exhibit a fatigue limit, although it may not be as well defined as steel. On the other hand, aluminum does not have a fatigue limit, and therefore aluminum bicycle frames can fail due to metal fatigue after a long enough time.
　　Titanium is extremely corrosion resistant. In fact, it can be used without painting the bare metal because it does not rust or corrode like steel frames or aluminum exposed to rock salt. This means you never have to worry about your titanium frame falling apart due to exposure to the weather.
　　The Ti 3-2.5 tubing is the high strength material used in the most advanced aerospace applications. It is drawn seamless tubing, which can be welded to join the tubes of the bike frame together. The tubes are cold worked to provide additional strength to the material, and through this process is tailored to provide the correct shape tubing for the frame design. This provides an extremely lightweight and strong racing machine, where the geometry of the frame is tailored by working the tube sets to create the perfect ride.
　　At Hang lun we take the design, fabrication, and material selection process very seriously, creating the best product possible for the intended application; making bikes go fast. These are just a few of the reasons why our frames are leading the industry in innovation and craftsmanship.
