The weight of a single layer of an aluminum coil depends on its thickness, width, and length. To calculate the weight, you can use the formula: weight = volume 脳 density. The density of aluminum is approximately 2.7 grams per cubic centimeter. If you know the dimensions of the coil, you can calculate its volume and then multiply by the density to find the weight. For example, if the coil has a thickness of 0.1 mm, a width of 1 meter, and a length of 100 meters, the volume would be 0.1 liters or 100 cubic centimeters, and the weight would be approximately 270 kg. However, without specific dimensions, it's impossible to provide an exact weight.
