Tungsten alloy automobile counterweight used in the car can adjust the center of gravity of the chassis, so that the center of gravity close to the ground so that the body can resist the upward airflow of air resistance in high-speed driving, maintain a smooth exercise. This greatly improves the maneuverability of the vehicle and the sensitivity of the control mechanism.
Tungsten alloy is used as the first choice of vehicle weight parts, mainly because it has the following series of excellent characteristics.
1. High density: the density of tungsten alloy is generally 16.5~19.0g/cm^3, which is equivalent to more than two times of the steel density, the tungsten alloy weight added to the car, can maintain the high performance of the car in the movement, provide a controllable system. The high density of tungsten alloy greatly reduces the physical size of components, takes up less storage space and is easier to transport.
2. Machinability: Because tungsten alloys are machinable, this gives car designers a lot of room to design.
3. Good ductility: W-Ni-Fe high density alloy has good ductility, the elongation of its sintered state can reach 10%~15%, after vacuum or atmosphere dehydrogenation treatment, the elongation can be increased to 20%~30%.
4. Good corrosion resistance and oxidation resistance: it can prolong the service life of racing cars and save costs.
5. Good weldability: can be brazed with copper and silver welding materials.
6. Environmental protection: tungsten alloy car weight is a substitute for toxic and harmful to the environment of high-quality products.
Tungsten alloy automobile counterweight according to the use can be divided into: automobile crankshaft counterweight and automobile balance counterweight. Automotive crankshaft counterweight is used to reduce the physical size of the engine and can be used in sports car engines. The counterweight is used on the chassis of a car to lower the center of gravity of the body so that it can be balanced at high speeds.
The choice of tungsten alloy counterweight block needs to consider the two important factors of vehicle type and weight, only in this way to ensure the stability of the body without increasing its burden.
