Abstract
An improved container featuring an aluminum end or panel having a tear open portion defined by score lines provided in an aluminum composite having a core composed of an aluminum alloy consisting essentially of 1 to 7% of one or more elements selected of the group of up to 3% copper, up to 4% magnesium and up to 1.5% manganese, the balance essentially aluminum and an aluminum cladding layer consisting of aluminum and, optionally, some amount of zinc but less than 1% with the cladding facing the contents of the container. The solution potential of the core and cladding are controlled in order to achieve the desired protection. A thermal treatment can be employed to control the electrochemical performance of certain composites.
