Application Of Titanium In Automobile -- Titanium Alloy Wheel Hub Bolt

With the popularization of automobiles, the market of refitting is booming. More and more auto lovers can not help thinking about how to make the car more personalized and more extreme. TIFAN gives a perfect answer - change the bolt.

The thousands of bolts all over the car seem unremarkable, but they are hailed as "industrial meters". The New York Times magazine has named the bolt one of the most important inventions of the past one thousand years. Unknown bolts play a decisive role in the performance and driving control of the car, while the ultimate excellent bolt, not only its mechanical strength, fatigue and corrosion resistance to meet the standards, but also to achieve light enough.

Automotive light weight has become the trend of the world automotive development. Experiments show that, if the vehicle weight is reduced by 10%, fuel efficiency can be increased by 6%~8%; vehicle kerb mass decreased by 100 per kg, 100 km fuel consumption can be reduced 0.3~0.6 liters, carbon dioxide emissions can be reduced by about 5 g / km; vehicle weight decreased 1%, fuel consumption can be reduced by 0.7%. In particular, under the weight of lightweight spring, can significantly enhance the seismic efficiency, improve grip, reduce inertia lifting control, its acceleration performance will be improved, the braking distance will be reduced. You can say "light"

As the most detailed and important part of a car, the wheel bolts, of course, are lighter and better as long as the strength and toughness are guaranteed. TIFAN (Eph titanium sodium) is China's first focus on automotive lightweight solutions for scientific and technological innovation of enterprises, headquarters and production base in Beijing, the introduction of the titanium alloy hub bolt is 45% less than the original bolt weight, strength increased more than 125%; is the industry's first full index reached even more than the titanium alloy car wheel bolts 8.8, 9.8 and 10.9 grade standard.

Is really "titanium" can be sultry, but not all of the titanium alloy can be used as raw material for bolt hub, hub bolt under high shear, high bearing capacity, and long period of fretting wear, also requires "toughness". Toughness represents the ability of materials to absorb energy during molding, deformation, and fracture. The better the toughness, the less likely the brittle fracture occurs, the higher the safety. Normally, the higher the strength of the same material, the lower the toughness, and vice versa. Thanks to the master and in-depth study on the application of scientific materials, the formation of a unique TIFAN titanium alloy material system and standard, and cooperate with the famous aviation enterprises developed special titanium alloy materials, both strength and toughness index were overall than the traditional steel bolt and common titanium alloy bolts.

Some leading car makers, such as Ferrari, have begun using titanium alloy wheel bolts on some models.
