Ironing is a sheet metal working or sheet metal forming process. It uniformly thins the workpiece in a specific area. This is a very useful process. It is used to produce a uniform wall thickness part with a high height-to-diameter ratio. It is used in making aluminium beverage cans.
Typical applications include marine, aircraft, architecture, general sheet metal work, heat exchangers, fuel lines and tanks, flooring panels, streetlights, appliances, rivets and wire. The exceptional corrosion resistance of 5052 alloy against seawater and salt spray makes it a primary candidate for the failure-sensitive large marine ...
Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements.Important grades also contain additives of magnesium, iron, nickel and silicon (AlCu(Mg, Fe, Ni, Si)), often manganese is also included to increase strength (see aluminium-manganese alloys).
T1 temper 6063 has an ultimate tensile strength of at least 120 MPa (17,000 psi) in thicknesses up to 12.7 mm (0.5 in), and 110 MPa (16,000 psi) from 13 to 25 mm (0.5 to 1 in) thick, and yield strength of at least 62 MPa (9,000 psi) in thickness up to 13 millimetres (0.5 in) and 55 MPa (8,000 psi) from 13 mm (0.5 in) thick.
An aluminium alloy (UK/IUPAC) or aluminum alloy (NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper , magnesium , manganese , silicon , tin , nickel and zinc .
A forming limit diagram, also known as a forming limit curve, is used in sheet metal forming for predicting forming behavior of sheet metal. [1] [2] The diagram attempts to provide a graphical description of material failure tests, such as a punched dome test. In order to determine whether a given region has failed, a mechanical test is performed.
In bottoming, the sheet is forced against the V opening in the bottom tool. U-shaped openings cannot be used. Space is left between the sheet and the bottom of the V opening. The optimum width of the V opening is 6 T (T stands for material thickness) for sheets about 3 mm thick, up to about 12 T for 12 mm thick sheets.
