three Temper of aluminum foil blanks

What are the three Temper of aluminum foil blanks?

The Temper of the aluminum foil blank is divided into three types: soft state (O), semi-hard state (H14, H24) and fully hard state (H18).

For soft state or hard state aluminum foils that require general mechanical properties, such as double foils and ordinary single foils, soft state or semi-hard state blanks can be selected.

For aluminum foils with special performance requirements, such as cable foils, wine label foils, air-conditioning boxes, etc., semi-hard or full-hard blanks can be selected. When selecting semi-hard blanks, the intermediate heat treatment process, chemical composition and final heat treatment process should be fully considered. The influence of the mechanical properties of the finished aluminum foil, the chemical composition should be fully considered when selecting the full-hard billet, and the influence of the final heat treatment process on the mechanical properties of the finished aluminum foil.

The weight of the aluminum foil blank mainly depends on the degree of mechanization and structural performance of the equipment. The heavier the stock roll, the higher the productivity. Therefore, under possible conditions, try to use blanks with larger coil weights
