What Is 8021 Aluminum Foil?

8021 aluminum foil is a high-purity aluminum alloy material with excellent electrical conductivity, thermal conductivity, corrosion resistance and plasticity. Its purity is as high as 99.5% or more, so it has good processing performance and forming performance. In the pharmaceutical industry, 8021 aluminum foil is widely used in pharmaceutical packaging because its surface can form a dense oxide film with good corrosion resistance and barrier properties, which can protect pharmaceuticals from the external environment.

What is its electrical and thermal conductivity?

As a high-purity aluminum alloy material, 8021 aluminum foil has excellent electrical conductivity and can effectively transmit and receive current. Therefore, it is a good choice for applications that require higher thermal conductivity, such as radiators, circuit boards, etc. Excellent material selection. At the same time, its thermal conductivity is also strong and can transfer heat quickly, helping to dissipate heat and prevent overheating.
