What is car aluminum?
Car aluminum, also called automotive aluminum, is an aluminum alloy material used in automobiles. Automotive aluminum used in engines can reduce weight by 30%, aluminum body is 40% lighter than steel products, and aluminum wheels can reduce weight by about 30%.
In recent years, due to the increasingly strict requirements for environmental protection and energy saving, automobile lightweight has become an overwhelming trend in the development of the world’s automobiles. The so-called light-weight of the automobile is to reduce the weight of the entire vehicle as much as possible on the premise of ensuring the strength and safety performance of the automobile, thereby improving the power of the automobile, reducing fuel consumption, and reducing exhaust pollution. Under such circumstances, automotive aluminum gradually began to be widely used.
Why do cars use car aluminum?
It has been more than 130 years since the birth of the automobile. In the development process of more than a century, fuel saving has always been the direction of the efforts of automobile developers. Among them, work hard on light weight, which is an effective way to save fuel. According to industry statistics, if the overall weight of the car is reduced by 10%, it can save 6% -8% of fuel, reduce fuel consumption by 0.3-0.6 liters per 100 kilometers, and reduce carbon oxide emissions by 5-8g. This is all thanks to automotive aluminum made from aluminum alloys.
Automotive lightweight materials are divided into two major categories of metals and non-metals. Metal materials mainly include high-strength steel and aluminum alloys, magnesium alloys and so on. Among them, car aluminum has many advantages. Its density is 1/3 of steel; it has good extensibility, corrosion resistance and easy recycling; and it has good castability and can be processed into different shapes. It is currently one of the popular lightweight materials. Many models currently use all-aluminum bodies.
Car aluminum for “four doors and two covers”
The quality of car aluminum used for car doors is only 10.2kg, while that of traditional steel doors is as high as 22.7kg, a drop of 55.1%. For the car door, car hood, and front and rear fenders of the car, the mature product currently developed is 5182 aluminum plate. Car aluminum 5182 aluminum plate has good stamping effect. From the perspective of customer response, after stamping, the aluminum plate has no cracks. 5182 aluminum plate, the thickness range currently produced by Mingtai can be 0.15-600mm, and the width range is 20-2600mm. (Customized according to customer needs)
Car aluminum for auto parts:
Auto parts alloy aluminum plate contains a wide range. Mingtai Aluminum has conducted research on automobile bottom guards and automobile gas storage tanks. Lightweight aluminum alloy products that meet the requirements include 5083, 5754, and 5052 alloy aluminum plates. It is important to mention here that 5083 aluminum plate and 5052 aluminum alloy are the most widely used in car aluminum car parts, and the effect is also very good.
Car aluminum for wheels:
Compared with car body, car aluminum is more widely used for aluminum alloy wheels. Aluminum alloy wheels stand out in the automotive industry due to their advantages of light weight, fast heat dissipation, good shock absorption performance and long tire life, and have huge development potential. The aluminum used for the wheels is mainly 6061 aluminum alloy. 6061 aluminum alloy is Mingtai Aluminum’s very mature technology for 6061 aluminum alloy. It can produce 0.30-600mm thickness and 150-2600mm width.
Car aluminum used in car air conditioning:
In the past, radiators in automobiles generally used copper alloys, that is, copper tubes. If car aluminum alloy aluminum fin heat sink is used instead of copper alloy, the quality can be reduced by 20% to 45%. The car aluminum heat exchanger is composed of an aluminum tube through which cooling water passes and radiating fins for heat dissipation. Aluminum tubes are generally made of 1xxx and 3xxx series aluminum alloys by extrusion and drawing. The heat dissipation fins are made of composite foil of 3xxx series and 6xxx series aluminum alloy core materials and 4xxx series and 7xxx series aluminum alloy brazing layers. There are many types of aluminum alloys, mainly 3003 alloy.
