1050 Aluminum Foil
1050 aluminum foil is an industrial pure aluminum foil with an aluminum content of no less than 99.5%, belonging to the 1000 series of commercial pure aluminum. It is also one of the most widely used pure aluminum foil materials. Due to its mature production process, stable performance, and controllable cost, 1050 aluminum foil has extremely high practical value in both industrial and civilian applications.
This aluminum foil is made from high-purity aluminum as the base material. The material is soft, with excellent ductility and formability, easily meeting the requirements for rolling, bending, lamination, and various other processing needs. At the same time, its natural oxide layer provides good corrosion resistance, allowing it to maintain stable performance in humid or general chemical environments.
As a representative grade of industrial pure aluminum foil, 1050 aluminum foil achieves a good balance between electrical conductivity, thermal conductivity, formability, and corrosion resistance. The "50" in the grade represents an aluminum content that reaches the 99.5% purity standard. This characteristic makes it an ideal choice for applications where high strength is not required but processing performance and service life are valued.
With its high cost-performance ratio and reliable performance, 1050 aluminum foil is widely used in packaging materials, electrical insulation, electromagnetic shielding, building insulation, and flexible composite materials. Under soft conditions such as H0, its flexibility is particularly outstanding, making it suitable for applications that require frequent bending or conforming.
