Aerosol can A dispenser that holds a substance under pressure and that can release it as a fine spray, usually by means of a propellant gas.
Chromium A grey, hard, and lustrous metal with the chemical symbol Cr.
Cold rolling Rolling below recrystallization temperature of the material to reduce the thickness as well as to obtain certain mechanical properties or surface structures.
Cupping The cutting out of discs and forming them into shallow cups.
Drawing The operation of reforming sheet metal without changing its thickness
DWI DWI cans are drawn and wall-ironed for height greater than diameter. They are always two-piece cans. Food cans are normally constructed from tinplate, whereas drinks cans are constructed from tinplate or aluminum.
Earing The formation of uneven or wavy edges to a deep-drawn can, due to the anisotropic yielding of a material. Since ears have to be trimmed and therefore represent wastage, alloys and processes are developed to minimize the effect.
Electrolysis Passage of electric current through a molten substance, resulting in chemical reactions at the electrodes.
Flanging Rolling or brushing process of producing a rim on the can ends.
Forge Shaping metal by using localized compressive forces.
Hot rolled strip Also referred to as hot strip or coil. Coil refers to a rolled up steel strip.
Hot rolling Passing of metal between a set of rolls, permitting large deformations with a low number of rolling cycles.
Lenticular 3D hologram when suitably illuminated it shows a three-dimensional image.
Lüders bands/lines Surface markings, often visible with the naked eye, that form across the surface of a steel sheet, etc. after being plastically deformed. They are caused by localized plastic deformation that results from discontinuous yielding.
Necking Tapering of hollow parts by means of a rolling or brushing can forming process.
Re-drawing Reforming a two-piece can to have smaller diameter and greater height, without changing its thickness.
Tin A malleable metal that is used to coat other metals to prevent corrosion. Chemical symbol Sn.
Tin-free steel Tin-free steel (TFS) is also known as chromed steel. It is obtained by coating the low-carbon steel with an ultra-thin layer of metallic chrome and then with a chromium oxide layer.
Tinplate A low carbon steel sheet, coated on both sides with a thin layer of tin, through an electrolytic process.
