Cold Working Sheet Metal

The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet.

Cold working sheet metal.

Since they are generally stronger and work harden more rapidly than the austenitic stainless steels the application of greater force is normally required to achieve the same amount of cold deformation. Hot working usually results in the refinement of grain structure whereas cold working merely distorts the grains and does little towards reducing its size. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls. Sheet metal cold working can be used to produce controlled surface finish.

Metal is said to be cold worked if it is mechanically processed below the recrystallization temperature of the metal. The process consists of a set of two or more rollers spaced closed together and the sheet or strip of metal is passed through them. Cold working refers to the process of strengthening metal by changing its shape without the use of heat. Cold working or cold forming is any metalworking process in which metal is shaped below its recrystallization temperature usually at the ambient temperature.

Be it manual or powered equipment we have the solutions you need. Such processes are contrasted with hot working techniques like hot rolling forging welding etc. The three series are 3xxx 4xxx and 5xxx. Most of cold working processes are performed at room temperature.

Cold rolling is often used commercially in order to produce sheet metal plates and bars. Cold working is a type of metalworking done by subjecting metal to enough mechanical stress to cause plastic deformation a permanent change in the metal s crystalline structure. Sheet metal machines quality fabrication equipment from a company you can trust from job shop to industrial grade fabrication shops around the world power up your sheet metal fabrication performance with coldworks equipment by fabrication solutions technologies fst. Like heat treatable aluminum alloys cold working aluminum alloys will be placed within certain series designations based on the type of alloying element that was added and the characteristics that the metal has.

It gets its name because it is done at temperatures below the metal s recrystallization point and alters the metal s structure through mechanical stress rather than heat.
