Standard Conditions and Finishes
The various industry "Standard Conditions and Finishes," which are produced by thermal, mechanical and chemical means, and in which bare, unmounted aluminum foil is available, are as alphabetically listed below:
Standard Conditions of Bare Aluminum Foil
Annealed Foil - Foil completely softened by thermal treatment.
Chemically Cleaned Foil - Foil chemically washed to remove lubricant and foreign material.
Hard Foil - Foil fully work-hardened by rolling.
Intermediate Temper Foil - Foil intermediate in temper between Annealed Foil and Hard Foil.
Roll of Foil - Foil in coiled form.
Sheets of Foil - Foil in rectangular form, sheared to size.
Standard Finishes of Bare Aluminum Foil
Bright Two Sides Foil (B2S) - Foil having a uniform bright specular finish on both sides.
Embossed Foil - Foil on which a pattern has been impressed by means of an engraved roll or plate.
Etched Foil - Foil roughened chemically or electrochemically to provide an increased surface area, for such uses as capacitors.

Matte One Side Foil (M1S) - Foil with a diffuse reflecting finish on one side and a bright specular finish on the other.
Matte Two Sides Foil (M2S) - Foil having a diffuse reflecting finish on two sides.
Mechanically Grained Foil - Foil mechanically roughened for such applications as lithographic plates.
Mill Finish Foil (MF) - Foil having a nonuniform finish which may vary from coil to coil and within a coil.
Scratch Brushed Foil - Foil abraded with wire or plastic/abrasive brushes to produce a roughened surface.
In addition to bare, unmounted foil, many producers offer various types of heat seal coated, protective coated, and laminated aluminum foil products.
