Află mai multe despre 8021 folie de aluminiu
“8021 folie de aluminiu” refers to 8021 alloy aluminum foil, which is a more common alloy type in the 8000 serie. 8021 alloy is a common type of aluminum alloy with high strength and plasticity. Folie de aluminiu 8021 is a thin sheet made of pure aluminum, which has good flexibility, thermal conductivity and electrical conductivity. It is widely used in food packaging, ambalaj farmaceutic, battery casing, thermal insulation materials and other fields.
What is the composition of 8021 alloy aluminum foil?
The main components of 8021 aluminum alloy include alloy additions of aluminum (Al), cupru (Cu) and a small amount of other elements.

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 sau 2700 kg/m³. 8021 aluminum foil is usually very thin, often less than 0.2 mm (200 microni) gros, and its density is close to that of pure aluminum.
8021 aluminum foil melting point
Punctul de topire al 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 grade Celsius (1220.5 degrees Fahrenheit).
