|
Tensile strength |
The ability to withstand tension |
|
|
Annealing |
Is a process that softens a metal and decreases internal stress, the metal temp is raised and cooled at 500F at 50D per hour thermal |
|
|
Thermally Conductive |
Enables the metal to carry out heat |
|
|
Electrical conductivity |
The measure or a materials ability to allow electron flow |
|
|
Coefficient of Expansion |
The property of a metal to expand when heated and shrink when cooled is called thermal expansion. The amount or expansion or contraction is predictable at specific temperature and is called... |
|
|
Elastic Limit |
The point beyond which the metal does not return to its original shape after a deforming force is removed. Lead, copper, and pure aluminum have very low ... |
|
|
Wrought |
Objects that are formed by physically working the metal into shape |
|
|
Cast |
Items are formed by pouring molten metal into molds |
|
|
Hot Working |
The process of forming metal at an elevated temperature when it’s in its annealed or soft condition |
|
|
Rolling |
Forming hot metal ingots with rollers to form sheets, bars and beams. |
|
|
Forging |
A process wherein a piece of metal is worked at temperatures above its critical range. It’s typically used to form intricate shapes and is accomplished through either pressing or hammering |
|
|
Pressing |
Used to form large and heavy parts |
|
|
Drop forging |
Hammering process whereby a hot ingot is placed between a pair of formed dies in a machine called a drop hammer and a weight of several tons is dropped on the upper die |
|
|
Hammering |
Forging usually done by a metal worker to physically hammer a piece of metal into its finished shape |
|
|
Smith forging |
Hammering the part to shape is referred to this |
|
|
Cold working |
Performed well below a metals critical temperature and ranges from a Manuel bending of sheet metal for skin repairs |
|
|
Cold working |
Performed well below a metals critical temperature and ranges from a Manuel bending of sheet metal for skin repairs |
|
|
Cold rolling |
Rolling of metal at room temperature to it’s appropriate size. Once this is done, the metal is pickled to remove any scale |
|
|
Cold drawing |
Used to make seamless tuning, wire, streamlined tie rods, and other forms of stock |
|
|
Density |
Mass per unit volume |
|
|
Yeild strength |
The ability of a meta to resist deformation |
|
|
Hardness |
The ability of a metal to resist cutting,penetration, or abrasion |
|
|
Mealibility |
The ability of a metal to be bent formed or shaped without cracking |
|
|
Ductility |
The ability of a metal to be shaped by drawing or pulling |
|
|
Strain hardening |
Mechanically working metals below their critical range is know as cold working and strain hardening |
