Metal Fabricators Terms
–
A steel to which one or more alloying elements—with the exception
of carbon and the commonly accepted amounts of manganese, silicon sulfur
and phosphorus—have been added to attain specific physical properties.
Common alloys include chromium, nickel, molybdenum, etc.
– A nonferrous metal
that is commonly used in the creation of light, strong and corrosion-resistant
alloys. Aluminum is an element that is primarily found in bauxite.
– A process that involves
the heating and cooling of a cold-rolled substrate, making it softer and
easier to form.
– The changing of the
shape of sheet metal by utilizing pairs of forming rollers in succession.
Bending changes the thickness of the metal only at the bend radius, at
which point a slight thinning occurs.
– A high-heat, metal-linking
method that uses a filler material to make a bond between two metals.
The filler is melted to a temperature just below the melting points of
the materials being joined.
– A solution
of chemicals often applied to various metals in order to inhibit corrosion.
– (http://www.cnc-machining.biz) A manufacturing process that automatically
shapes or forms metals or other materials into highly precise parts.
CNC machines utilize specialized software in conjunction with CAD/CAM
software systems to instruct the tooling to execute the exact movements
necessary to create the part.
– A flat-rolled
metal sheet whose final thickness was achieved by rolling it at room temperature.
– A chemical
film that is applied to a metal prior to the painting process.
– The deterioration
of a metal due to a chemical reaction or oxidation. Rust is a common form
of corrosion.
– A process in which
a metal is penetrated or opened using a sharp edge. Metal sheets are almost
always cut from a larger source prior to fabrication.

– The application of a powerful die to a metal blank. Pressure from
the stamping device is often applied by a mechanical or hydraulic
press.
– The ability of a
metal to endure change without fracturing. Hardness and the tensile strength
of the metal often determine its ductility.
– A term that encompasses
many processes, which are used to shape or mold a metal piece into a desired
configuration.
– A metal sheet
processed to its absolute thickness by rolling on a specialized hot-rolling
machine.
– Eliminating distortions
of a rolled sheet by flattening the material.

– The process of applying a powder consisting of solids to a material
surface and then heating the powder above its melting point to create
a uniform film.
(http://www.rollformedparts.com)
– A process in which sheet metal is continually deformed by passing
it through a series of rolls.
(http://www.stainless-steel.us)
– A wide variety of corrosion-resistant steel that contains at least
10% chromium and to which varying amounts of other elements, such as nickel,
molybdenum, titanium and niobium, have been added.
– Also referred
to as “ultimate strength,” it is the maximum amount of stress
a material can endure.
– The joining of two
metals accomplished by heating them enough to melt into one another. Welding
differs from brazing in that it does not require a filler material to
create the actual bond.
