Titanium and titanium alloys are characterized by low density, excellent mechanical properties, good biocompatibility, corrosion resistance, high temperature resistance and low temperature toughness, etc., and are currently used in a large number of automotive manufacturing fields. With the accelerating pace of the automotive industry in pursuit of more efficient and environmentally friendly, titanium alloy is becoming the future choice of lightweight and high performance in the automotive industry by virtue of its excellent performance.
1. Advantages of Titanium Alloys for Lightweighting
Titanium Alloy Aerospace have a low density, only about 60% of steel, but a strength close to or even exceeding that of many alloy structural steels. This characteristic makes titanium alloys an ideal material for achieving automotive lightweighting. For example, in modern automobile manufacturing, engine connecting rods made of titanium alloys can reduce weight by 15% to 20% compared to steel connecting rods. This lightweighting not only reduces the overall mass of the vehicle, but also reduces fuel consumption and improves fuel economy.Yesino provide Titanium Bar, Titanium Sheet, Titanium Plate, Titanium Forging and other titanium product.
2. Heat and corrosion resistance of titanium alloys
Titanium alloys maintain the required strength at high temperatures and have excellent corrosion resistance. This gives titanium alloys a significant advantage in high-temperature, highly corrosive environments such as engines. For example, turbocharger rotor rotors made of titanium alloys can be operated for long periods of time in high-temperature exhaust gases above 850°C without significant performance degradation. In addition, titanium alloy in the humid atmosphere and seawater media work, its corrosion resistance is also far better than stainless steel, can resist pitting, acid corrosion and stress corrosion and other forms of corrosion.
Application of titanium alloys
1. Engine connecting rod: Ferrari 315LV8 model is one of the earliest applications of titanium alloy connecting rod of the car. The lightweight design of this connecting rod not only improves the power performance of the engine, but also reduces fuel consumption and emissions.
2. Engine valves: Compared with steel engine valves, titanium engine valves are lighter in mass and have a longer service life. For example, the mass of some titanium valves can be reduced by about 30% to 40%, while the engine limit speed can be increased by about 20%.
3. Body frames: Japanese automakers use titanium alloys to make body frames to reduce body weight and improve the driving experience. Such frames are not only strong and tough, but also have excellent corrosion resistance. 4.
4. Aerospace: Titanium alloys are widely used in the aerospace industry. For example, about 15% of the fuselage of the U.S. Boeing 787 Dreamliner is made of titanium alloy, which not only reduces the overall mass of the airplane, but also improves its flight performance and safety.
Summarization
The above examples show that titanium alloys have significant advantages in the automotive industry. Its lightweight, heat-resistant and corrosion-resistant properties make titanium alloys an important material for realizing automotive lightweighting, improving performance and reducing costs. With the continuous progress of preparation technology and cost reduction, titanium alloy will play a more important role in the automobile industry and promote the technological progress and industrial upgrading of the automobile industry.
