Electrolytic aluminum is a method of smelting metallic aluminum. Alumina is usually decomposed into metallic aluminum through a large current in an electrolytic tank.
Aluminum ingots are divided into three types according to their composition: high-purity aluminum ingots, aluminum alloy ingots and aluminum ingots for remelting; according to shape and size, they can be divided into round ingots, plate ingots, strip ingots, T-shaped ingots, etc.
Aluminum is a silver-white metal, ranking third in content in the earth's crust after oxygen and silicon. Aluminum has a low density, so it is called a light metal. Aluminum is a non-ferrous metal with high production and usage, second only to steel in the world. The density of aluminum is about 1/3 of the density of steel and copper. Because aluminum is light, it is often used in manufacturing, trains, subways, cars, airplanes, ships, rockets and other land, sea and air vehicles to reduce weight and increase load capacity. Similarly, aluminum also plays a prominent role in military products.
Alumina, also known as aluminum oxide, is in the form of white powder. Raw aluminum is the liquid aluminum produced during the electrolysis process and has not undergone any treatment such as precipitation. Raw aluminum can be turned into aluminum ingots by entering the cast aluminum ingot model body for cooling treatment. Therefore, alumina is the raw material for producing aluminum liquid, electrolytic aluminum is the process, raw aluminum is the aluminum liquid in the electrolysis process, and aluminum ingot is an aluminum product that is ultimately sold on the market.
