Aluminium foil GOST 618-73 intended for technical purposes, primarily, for thermal, hydro- and sound.
Aluminum foil for capacitors produced in accordance with GOST 25905-83, aluminum foil food - according to GOST 745-2003.
1.1 According to the state of the material, technical foil is divided into the following types:
M - soft (with annealing);
T - hard (no annealing).
2.1 Foil thickness and tolerances in the thickness indicated in the table correspond to 1.
2.2 foil width - from 10 to 1500 mm.
