Question 1: How much weight can aluminum cars reduce?
Answer: In general, the weight of vehicles is reduced by 10%, and fuel can be saved by 8%; Every 1kg of aluminum used in transportation can reduce 20kg of carbon dioxide emissions. The density of aluminum is about 1/3 that of steel. When aluminum is used to replace steel to make automobiles, the weight of the whole vehicle can be reduced by 30%~40%. When making engines, the weight of aluminum radiator can be reduced by 30%~40%. Compared with the same copper products, aluminum radiator is 20%~40% lighter, and aluminum wheels can be reduced by about 30%.
Question 2: Aluminum is lighter, is it unsafe?
Answer: The impact force absorbed by the all aluminum body is greater than that of steel, so it can better ensure the safety of drivers and passengers in the car. Because of the excellent characteristics of aluminum, aluminum alloy has been widely used in various parts of automobiles today, such as dashboard and engine bracket, aluminum alloy wheels, suspension system parts, bumper crash beam, cylinders, doors and heat exchangers.
Question 3: If aluminum replaces steel, wouldn't the cost of buying a car go up?
Answer: At present, the most economical and feasible lightweight plan is to replace steel with aluminum, because the saved fuel cost is more economical than the increased vehicle purchase cost.
According to the calculation of Founder Securities Research Institute, every 1kg aluminum material used in cars can reduce the weight by 2.2kg. According to the calculation of ordinary household cars, nearly 2 liters of gasoline can be saved every year. With the current oil price, the increased cost of using aluminum instead of steel can be recovered in about 1.6 years.
Question 4: Is aluminum green?
Answer: Aluminum is the most environmentally friendly green metal with good processing performance, physical performance, mechanical performance and corrosion resistance. Because of its excellent comprehensive performance, aluminum is indispensable to all important aerospace vehicles, packaging containers, pots and pans.
