Cold Working Sheet Metal

Cold working refers to the process of strengthening metal by changing its shape without the use of heat.

Cold working sheet metal.

Touching a hot piece of sheet metal can burn an employee s hands or body of course sheet metal is equally conductive to cold temperatures as it is for heat. Cold working or cold forming is any metalworking process in which metal is shaped below its recrystallization temperature usually at the ambient temperature. 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. 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.

Most of cold working processes are performed at room temperature. Employees handling sheet metal outdoors during the winter may experience frostbite from touching it breathing in sheet metal dusta lesser known danger of working with sheet metal is the. The three series are 3xxx 4xxx and 5xxx. Hot working usually results in the refinement of grain structure whereas cold working merely distorts the grains and does little towards reducing its size.

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. Metal is said to be cold worked if it is mechanically processed below the recrystallization temperature of the metal. The haynes and hastelloy alloys can be readily formed into various configurations by cold working. Sheet metal cold working can be used to produce controlled surface finish.

Cold rolling is often used commercially in order to produce sheet metal plates and bars. Such processes are contrasted with hot working techniques like hot rolling forging welding etc. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls.
