3003 Aluminum Foil

3003 aluminum foil is made from aluminum alloy 3003. It has manganese as the primary alloying element, which gives it multiple advantages like excellent rust resistance, good ductility, and the ability to be readily machined. 3003 aluminum foil is found in nearly every aspect of our everyday lives from lunch box container foil to making bakery molds. Electrolytic capacitors that are used in nearly every type of consumer electronics device need 3003 electronic foil as a crucial component.

Our aluminum alloy 3003 foil can be customized according to customer specifications and are available at competitive prices. At Inquivix Technologies, we utilize a state-of-the-art flatness control system in our rolling processes to ensure all of our foil products are manufactured to the thickness required whilst meeting accepted industry standards of quality.

Material Properties of Aluminum Alloy 3003

Moderate Strength

3003 is a medium-strength alloy that is 10% stronger than alloys in the 1xxx series. While it is not heat-treatable, it is possible to increase hardening through cold working. There are a variety of tempers available. Depending on the cold working method used, mechanical properties like strength can be improved at the cost of plasticity.

High Plasticity And Welding Performance

3003 supplied by Inquivix Technologies has high plasticity, especially in its annealed temper. This makes the foil very easy to be processed into the desired shape of the end product. Container foil needs to be resistant to cracking during the stamping process when it’s shaped into a multi-cavity structure. 3003 foil has the desired strength and elongation properties to be useful here.

Very Good Corrosion Resistance And Dielectric Properties

The oxide layer that forms on the surface of aluminum 3003 foil is what provides corrosion resistance to most types of acids and organic matter. Even more importantly, this oxide layer has a high dielectric constant, and its thickness could be controlled. These properties combined with 3003 foil’s easy formability make it useful in making the cathodes of electrolytic capacitors at a range of capacitor values.

Can Be Used as a Core Material for Aluminum Honeycomb

Our 3003 foil can also be used as the base material in the manufacture of aluminum honeycomb panels. These honeycomb panels have a high strength-to-weight ratio, making them useful in automotive, aerospace, industrial manufacturing, and even construction applications.
