8021 aluminiumfoliens densitet
The density of aluminum foil can vary slightly depending on its thickness and manufacturing process. As a general guideline, the density of aluminum is approximately 2.70 g/cm³ eller 2700 kg/m³. 8021 aluminum foil is usually very thin, often less than 0.2 mm (200 mikron) thick, and its density is close to that of pure aluminum.
8021 aluminum foil melting point
The melting point of 8021 aluminum foil is the same as that of pure aluminum because 8021 is an alloy mainly composed of aluminum. The melting point of pure aluminum is approximately 660.3 grader Celsius (1220.5 degrees Fahrenheit).
