Abrasion Resistance Ability of a coating to withstand rubbing, scraping and eroding forces.
Abrasive Sharp mineral particles, used for metal removal.
Abrasive Media Matrix used to carry the mineral particles for the purpose of material removal.
Acidic Etching Removal of surface contamination by corrosive treatment.
Adaptor A block used to mount a form tool to a slide.
Air Bending Forming operation in which a metal part is formed without the punch and die closing completely on the part. See Press Brake Chapter.
Air Hardening Steel An alloy steel which will form martensite with high hardness when cooled in air from its proper hardening temperature.
Alloys Base metal with other metal or non-metal constituents melted together into a new molecular structure.
Alodine Commercial trade name for a chromate conversion coating over aluminum.
Aluminum Alloy Pure aluminum which has been melted together with other constituents to achieve specific physical and mechanical properties.
Aluminum Oxide Hard mineral of aluminum and oxygen (AI03) used as an abrasive.
Annealed Softest possible state of any material. Annealing, Full -Heat treating process wherein metal is heated to a temperature above its critical range. held at that temperature long enough to allow full recrystallization, then slowly cooled through the critical range. Annealing removes working strains, reduces hardness, and increases ductility.
Anode Positively charged electrode.
Anodizing Process of applying a controlled oxide layer to the surface of aluminum.
Archive The storage of files in the form of tape or disk for long periods of time.
Arcs Partial circles used to describe rounded corners of material and show bends in material. Artificially Aged -Hardening process of material accelerated by temperature.
ASCII Acronym for "American Standard Code for Information Interchange."
Austempering A heat treating operation in which austenite is quenched to and held at a constant temperature (usually between 450°F and 800°F) until transformation to bainite is complete. In some steels at certain hardness levels, bainite is tougher than quenched and tempered structures.
Austenite The solid solution in which gamma iron is the solvent. Austenite is a structure and does not refer to composition. Austenite is the structure from which all quenching heat treatments must start.
Austenitic Stainless Steel -Non-magnetic stainless steel. Not hardenable through heat treatment: good corrosion resistance.
AutoCAD A brand name of CAD software prevalent in the marketplace.
Automatic Spinning The art of forming metal over a mold using an automatic (Computer Controlled or Template) spinning lathe.
Auxiliary Slide A bed mounted, cam operated slide typically used for forming on a slide forming machine.
Disclaimer: This glossary is designed to provide a practical, easy-to-use guide to terminology presently used in the context of metal stamping. It is intended to provide assistance and should not be viewed as a definitive source. We have made every effort to present accurate and up-to-date information. The metal stamping area is complex and rapidly changing, and it would be impossible to include every applicable term and acronym. Therefore, use the glossary as a resource, not as an authority. Users should refer to standard texts and reference works for more detailed analyses of the definitions presented.
