Aluminum Is More Expensive Than Iron Are Aluminum Cans Cheaper Than Iron Cans?

Although the reserves of aluminum in the earth's crust are more than that of iron, the production process of aluminum is much more complicated than that of iron. Aluminum is a relatively active metal element, and smelting requires electrolysis. Iron can be restored. The cost of carbothermic reduction is significantly lower than that of electrolysis, which is extremely energy-intensive, so the cost of consumption in the entire production process is higher than that of iron. Therefore, aluminum is obviously more expensive than iron, so it is more expensive, so the price of aluminum is higher than that of iron.

On the market, Wanglaoji, Babao porridge, Red Bull, etc. use relatively hard iron cans, because the packaged material is not under pressure, and aluminum cans are easily deformed. Iron cans are also called three-piece cans in the industry. The production process of iron three-piece cans is mostly lithographic printing, then cutting and then welding into circles. First, the top or bottom cover is fitted in the can factory, and then filled after filling. on the corresponding bottom or top cover.

The advantages of aluminum cans are that they are not easily broken, light in weight, and opaque to light. Common carbonated beverages on the market (cola, beer, etc.) use aluminum cans because aluminum cans are not easily corroded by acid, and aluminum cans are easy to form and relatively inexpensive to manufacture. The pressure in the soda is higher than the normal pressure, under the action of the pressure, there is no need to worry about deformation. Moreover, the aluminum can can ensure the pressure of carbon dioxide in the soda, so that the soda can achieve a better taste effect. Therefore, a strong and durable aluminum can is required to prevent deformation during transportation and storage. Aluminum cans are not made of pure aluminum, but aluminum alloy. Most of the domestic processes are stamped from aluminum coils, then roller printed, with easy-to-open lids, which are also called two-piece cans in the industry.

Although the price of aluminum is relatively high, switching to aluminum cans saves costs. One is that aluminum cans are lighter than iron cans, so the cost of a single can decreases. The second is that aluminum cans are two-piece cans and iron cans are three-piece cans. Tanks also save costs. When selling scraps, aluminum cans are more valuable than iron cans, because aluminum cans are easy to recycle and reuse, while iron cans are tin-plated plates with a layer of tin on them, and ordinary small factories don’t have that process for recycling.

More and more consumers are concerned about the impact of PET plastic bottles on the environment. At the same time, the scientific community and environmentalists are increasingly concerned about PET bottled water. The launch of cans is just in time, 100% can be recycled again.
