1050 Aluminum Foil

An aluminum alloy number in the 1xxx series means that 1050 is one of the purest alloys used for commercial purposes. Its aluminum composition is at 99.5% and it is the most electrically conductive alloy in its group. Other useful properties include corrosion resistance, lightweight, thermal conductivity, and smooth surface quality. This makes 1050 aluminum foil a crucial component used in a wide variety of industrial applications like transformer winding and food packaging.

Inquivix Technologies is the leading supplier of industrial-grade 1050 aluminum foil to secondary battery manufacturers who utilize it to produce their lithium-ion battery cathodes. Our foil can be made to customer specifications in the standard tempers, thickness, and width required through hot or cold rolling. All our foil products are carefully packaged to industry standards using a wooden pallet, and waterproof plastic covering to ensure it is delivered to our customers securely.

Material Properties Of 1050 Aluminum Alloy

The Most Economical Conductive Alloy

Since 1050 alloy is mostly aluminum, there are not many other chemical elements needed to produce it. This makes for a simpler production process than other more heavily alloyed products, making 1050 one of the most affordable alloys available that exhibit good electrical conductivity. This makes our 1050 aluminum foil invaluable for making lithium-ion battery cathodes, and the transformer strip in dry-type transformers.

Good Corrosion Resistance

1050 is resistant to corrosion, and when combined with its high ductility, low density, sealing tightness, and heat-insulating properties, the foil becomes a great material for making lightweight containers. These containers could be designed to carry food, medicine, pesticides, cosmetics, and even hair care products. 1050 aluminum foil is also widely used for cable shielding.
