structural materials

Tensile strength

The resistance of a material to breaking under tension

Yield strength

The ability of a material to resist deformation

Malleability

Capability of being shaped or extended by hammering, forging, etc.

Ductility

The ability of a material to have its shape changed without losing strength or breaking

Brittleness

The property of a material that fractures when subjected to stress but has a little tendency to deform before rupture

Conductivity

The measure of the ease at which an electric charge or heat can pass through a material

Expansion

The action of becoming larger or more extensive

Elasticity

The ability of an object or material to resume its normal shape after being stretched or compressed

Toughness

Ability to resist tearing/breaking when bent/stretched

Fusibility

How easy a material will melt with heat or the ease with which a material will bond with another

Density

Mass per unit of volume

Hot-working

Processes where metals are plastically deformed above their recrystallization temperature

Cold-working

The process of strengthening metal by changing its shape without the use of heat

Extruding

A forming process in which we force a metal (either hot or cold) through a die

Rolling

A metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property

Forging

The process in which metals are formed and shaped using compressive forces

Pressing

The process of forming a shape from a metal sheet, coil or tube, using a press tool or stamping dies

Drop Forging

A forging process in which the hammer is raised and then it is dropped on the workpiece to deform it into a desired shape

Cold Drawing

Metal drawn out into a wire or bar while cold

Extrusion

A metal forming process in which a work piece, of a certain length and cross section, is forced to flow through a die of a smaller cross-sectional area, thus forming the work to the new cross section

Solution Heat-Treatment

Process of heating certain aluminum alloys to allow the alloying element to
mix with the base metal (Soaked/Bath)

Precipitation Heat-Treatment

Metal is re-heated and allowed to soak from precipitation/shower for specific
period (Develops into hard, strength, and corrosion resistant)

Ferrous metals

Any metal that is primarily composed of iron and has magnetic properties

Shear Strength

The ability to resist opposing forces

Bearing Strength

The ability of a joint to withstand distortion

Allotropic Metal

A metal that can exist in one lattice structure, depending on temperature
