ABSTRACT:
This invention relates to a wrought aluminum alloy, to its use for making semifinished and finished products and to processes of improving the properties, particularly the strength properties, of semifinished and finished products made of that alloy.
The efforts to improve the properties of aluminum alloys are often successful but restrict the field of application of the material; this is undesirable in view of the need to save raw materials and energy. For this reason a wrought aluminum alloy is desired which has a very wide field of application and which can be made to have properties in a wide range, possibly as a result of a processing under different conditions. The manufacture and recycling of such alloy should not involve special difficulties and the alloy should require only unproblematic alloying elements which are conventionally used with aluminum. Specifically, the desired alloy should be suitable for the manufacture of cans for beverages (can bodies and covers) and for the manufacture of semifinished products which can be soldered and enameled.
