8021 aluminum foil density
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 or 2700 1/m.. 8021 aluminum foil is usually very thin, often less than 0.2 Te mau mana'o tauturu no te (200 Te mau nota) Te mau mana'o tauturu no te, and its density is close to that of pure aluminum.
8021 aluminum foil melting point
Te mana'o tumu o te 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 degrees Celsius (1220.5 degrees Fahrenheit).
8021 aluminum foil vs 8011 aluminum foil
8021 e 8011 aluminum foils are similar in many ways as they both belong to the 8xxx series of aluminum alloys commonly used in a variety of packaging applications.
