Gently heating a hardened metal and allowing it to cool slowly, producing a metal that is

still hard but also less brittle.

is the process in which metals are cooled rapidly after heating

It is the process of when work material is plastically deformed by compressive forces

between two constantly spinning rolls.

The metal drawing process in manufacturing industry is usually performed cold. Cold

working will impart the drawn product with accurate tolerances, favorable grain

structure, improved material properties and good surface finish.

Involves shaping metals using localized, compressive forces after heating the metal to

a point where it's malleable.

A mold is formed into the geometric shape of a desired part. Molten metal is then poured

into the mold, the mold holds this material in shape as it solidifies. A metal casting is

created. Molds can be classified as either open or closed. An open mold is a container,

like a cup, that has only the shape of the desired part. The molten material is poured

directly into the mold cavity which is exposed to the pen environment.

Is a manufacturing process also known as pressing, includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press that includes blanking, piercing, embossing, bending, flanging, and coining

is a term applied to certain aluminum products, refers to the protective coating

(cladding) applied, primarily for corrosion resistance, to thin sheets of an alloy whose corrosion resistance has been decreased by the constituents added to give strength and other characteristics.

This is rigidized sheet fabricated of special aluminum alloys specifically developed for this purpose. It usually consists of an aluminum alloy core of one type clad with another, highly corrosion-resistant aluminum roofing and siding

rolled to a thickness of 0.005” (above 0.005” it is technically considered to be sheet), used mainly for thermal insulation and vapor barriers

most commonly used for things like bridges, skyscrapers, shipping containers, railways, large pipes, tunnels, and cars. Their magnetic properties are also useful in the manufacturing of electrical appliances like refrigerators.

• tough,

• malleable silvery-white metal that is

• soft and ductile as copper

• it is easily magnetized

• is the most magnetically permeable of the metals

is almost pure iron with less than 0.1% carbon, usually not more than 0.05% is poured while molten into forms

usually refers to plain carbon steel which is defined as alloys of iron and

carbon which do not contain more than 2% carbon and which are made in malleable or ingot form.

is a method to join metals, to make electrical connections, to seal joints hermetically with another lower melting metal or alloy called the solder.

is the process by which two metals are so joined that there is an actual union of the

interatomic bonds. This may be brought about by close contact, heating, pressure, adding

molten metal, or combinations of these methods. The resulting joints are as strong or

stronger than the metals joined.

is a type of soldering in which the operating temperatures are higher (but lower

than in welding) and in which stronger and higher-melting alloys are used to fill the joints, which consequently are stronger than ordinary soldered joints. The bond is obtained by alloying between the brazing material and the surface of the joined metals.

refers to the glass that is installed in the window frame. One sheet of glass is a single glazed window, two glass panels create a double- glazed window and so on.

A hard brittle inorganic substance, ordinarily transparent or translucent; produced by melting a mixture of silica, a flux and a stabilizer; while molten, maybe blown, drawn, rolled, pressed or cast to a variety of shapes.

This glass is made by adding ingredients to the mix used in making regular slate glass so that the finished product is pale bluish-green or gray.

Because of its chemical composition, this glass absorbs a significant percentage of the sun's radiant energy, thus reducing the build-up of heat within the building.

This consists of two sheets of plate or sheet glass, separated by an air space, and joined around the edges to produce a hermitically sealed unit.
