7075 aluminum sheet is a cold-processed aluminum forged product that is often used in applications where corrosion resistance and oxidizing requirements are high. Good usability, excellent interface characteristics, easy coating and good processability. Can be used on low pressure weapons, wheels and aircraft joints.

In order to meet the requirements of safer, more energy-saving, lower noise and more stringent emission of pollutants, aluminum alloy wheels are developing in the direction of large diameter, light weight, wide rim, high strength and more beautiful. However, the aluminum alloy wheel market in North America For example, in the past few years, the diameter of the hub was still 13 to 14 inches. The current mainstream market is 15-16 inches or even 17 inches. As shown in Table 4, it can be seen from Table 4 that the 16-inch wheels It has the largest market share and the fastest growth. It has occupied 38.3% of the wheel market since the 19th century, and rose to 45% in the 20th century, accounting for 57.7% in the 21st century. Followed by 15, 17-inch wheels, accounting for 27.62% and 11.77% of the total market share. 18, 19, 20-inch large diameter wheels are also on the market.

It is predicted that in the next few years, 18-inch diameter wheels will become the standard configuration for car wheels. Wheel manufacturers have begun to arrange production lines for 22, 24 inch and above wheels to meet the latest demands in today's market. Large-diameter wheels combined with tires are more modern, domineering and more stylish than small-diameter wheels and tires. Due to the large diameter and wide rim, the contact area between the tire and the ground is larger, thereby increasing the adhesion and friction between the car and the ground, so that the handling performance of the car is better and the safety of the car is improved. General requirements are matched to flat tires. However, large diameter and wide rims also have the adverse effect of accelerating tire wear. In order to reduce the weight of the wheel and improve the strength, the forging process and the assembly process are generally used to produce the wheel, which can reduce the weight by about 20%. Wheels can also be made from high strength magnesium alloys and titanium alloys. But it will increase the cost accordingly.

In order to reduce the wheel noise, some are made of 7075 aluminum plate between the spoke and the rim. It can greatly reduce wheel noise and improve vehicle handling stability. In order to make the wheels more beautiful, chrome plating, polishing, painting, dusting, stainless steel or plastic hub caps, die-casting patterns, and improved wheel design patterns are generally used. Spinning aluminum hubs are not subject to dimensional constraints, aesthetics, performance, safety, material saving, etc., and their development momentum is good. They are advanced forming technologies, and their technical level has basically matured. The company's attention is gradually shifting to mass production.

Of course, if it is for the consideration of the price of aluminum plate, you can also choose 6061 aluminum plate as the material of the wheel, because the price of 7075 aluminum plate is 1-2 times higher than the price of 6061 aluminum plate. Of course, the hardness of 7075 aluminum plate is considered from the aspect of hardness. Higher and stronger. How to choose which aluminum plate to choose in the future market, we will wait and see!
