Different annealing process of aluminum foil

Different annealing process of aluminum foil

The annealing process system of aluminum and aluminum alloy sheets and strips should be determined according to the needs of the pressure processing process and the user's requirements for the mechanical properties of the finished product (ie alloy state).

A aluminum foil stock annealing

Before cold rolling, the hot-rolled slab generally needs to be annealed (also known as pre-annealing); the cast-rolled slab does not need to be annealed.

B Intermediate annealing

Intermediate annealing refers to annealing during cold working deformation.

C Finish annealing

The final annealing after the sheet and strip is rolled to the finished thickness is called finished annealing.

When the finished product is annealed, the annealing process must be strictly controlled to ensure that the mechanical properties of the material meet the requirements of technical conditions. According to the different requirements of mechanical properties, finished annealing is divided into two types: complete recrystallization annealing and incomplete recrystallization annealing.
