Forming Aluminum Sheet

Remember all this relates only to air forming.

Forming aluminum sheet.

Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal. Hillman 12 in x 24 in cold rolled steel expanded sheet metal. Item 168753 model 11786. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered.

Follow along as i demonstrate how you can begin shaping metal with hand tools only. Hydroforming is a cost effective way of shaping ductile metals such as aluminium brass low alloy steel and stainless steel into lightweight structurally stiff and strong pieces. Thicknesses can vary significantly. How can you go about shaping metal with hand tools alone.

Welcome to the latest how to installment from jay roche at special 79 barnstorm cycles. Bending is a delicate and demanding process most of the time and common fabricating processes require a degree of formability that make your choice of proper alloy critical. In high purity forms aluminum is soft and ductile. Most general use aluminum alloys have elongation percentages ranging from 10 percent up to perhaps 25 percent.

This tech tip is related to their sportster project but can be used on anything you might be working with that requires something built out of aluminum sheet. In this metal forming process a sheet of metal is passed through perforating scissors where it is cut and stretched into a pattern. This forming process is commonly used for manufacturing fences catwalks platforms grating etc. Aluminum strains locally meaning that it has poor stretch distribution as well as poor elasticity.

The applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail. By doing so the sheet can be bent or stretched into a variety of complex shapes. Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. Which aluminum alloy bends the best is a a common question customers want the answer to.

If i could give one bit of advice to those forming aluminum it would be to limit extensive stretching in small areas. Usually a diamond shaped mesh is preferred as it has a structural advantage over other shapes. Instead you actually form a parabola an effect that becomes especially apparent on profound radius bends in which the radius is more than 10 times the material thickness. One of the largest applications of hydroforming is the automotive industry which makes use of the complex shapes made possible by hydroforming to produce stronger lighter and more rigid unibody structures for.
