Abrasion (fr: Abrasion): The process of scratching, scuffing, rubbing away or wearing down. It can be intentionally imposed in a controlled operation, or it can be an undesirable effect of exposure to normal use or to various elements.


AISI (fr: AISI): The abbreviation for American Iron and Steel Institute, one of the oldest trade associations in the United States (1855). It was developed for collecting and disseminating statistics and information, carrying on investigations, providing a forum for the discussion of issues and generally advancing the interests of the metal industry.


Alloy (fr: Alliage): A substance with metallic properties that is composed of two or more chemical elements, with at least one of the elements being a metal.


Alloy steel (fr: Acier allié): Steel that contains additions of elements other than silicon, manganese, sulfur, phosphorus, or in which silicon and manganese are present in large amounts to of improve or alter any of the physical or mechanical properties of the steel.


Aluminizing (fr: Aluminiser): The process of coating steel with aluminum; it generates similar results to galvanizing and increases heat resistance.


Aluminum (fr: Aluminium): A silvery-white, soft, nonmagnetic and ductile metal. Aluminium is known for its low density, its ability to resist corrosion and is the most widely used non-ferrous metal. Its major uses are in the following industries: building & construction, transportation, packaging, electricity-related uses, household item production.

Angles (fr: Angles): A standard long product available in steel, aluminium and other metals, mainly used in industrial applications like: machinery & equipment frames (Braces and Corners), transportation (Frames and Corners), support frames that require bolting, riveting, welding; also, on bridges and buildings and for general structural use in construction. The arms of the angle may be equal or unequal.

Annealing (metallurgy) (fr: Recuit – métallurgie): A heat treatment process that alters the physical properties of metal to increase its ductility and reduce its hardness, thus making it more workable. The process involves the heating of the material above its recrystallization temperature, maintaining a temperature suitable for working the metal and finalizing with cooling.


Anodizing (fr: Anodisation): An electrolytic passivation process that coats the metal with a decorative, durable, corrosion-resistant, anodic oxide finish. Anodizing is used primarily with nonferrous metals, mostly aluminum. Aluminum oxide is not applied to the surface like paint or plating, it is integrated with the aluminum substrate, so it cannot chip or peel. Its structure is highly ordered and porous, which allows easy coloring and sealing. Anodized finishes have made aluminum one of the most widely used materials today in the production of consumer, commercial and industrial products.


ASTM (fr: ASTM): American Society for Testing and Materials (ASTM) is an international standards organization that develops and publishes technical standards for a wide range of materials, products, systems, and services.
