0,1 mm x 1000 mm hard alufoil in 25 m roll

Stucco Alufoil 0,1 mm x 1000 mm, hard, in 25 m reel

0,2 mm x 1000 mm soft alufoil in 10 m rollThe hardness of the aluminium refers to mechanical properties. The hard aluminium foil is stronger: it has higher tensile strength than a soft foil and a bit lower elongation. Soft foil is easier to bend and it holds the new shape better. The surface of soft foil is cleaner. The surface of hard foil is also clean but might contain residues of rolling oil. (it usually doesn't happen) If you don't know which to select you most probably need soft foil.
