What is formability in sheet metal?

measure of the capability of sheet metal to be deformed into a desired shape. Desired shape should have no splits, wrinkles, excess thinning and should retain desired shape repeatably. Measures of formability are obtained using FEA analysis and Circle Grid analysis and the forming limit diagram.

increasing the wall angle of the design improved the formability of the part by decreasing the strain in the wall

A higher tensile grade steel would decrease the formability of your design requiring a product change

using more lubrication was not a desirable way to improve the formability since it made the manufacturing operation too costly

Should not be confused with Ductility, since metals with high ductility may show highly non-uniform thinning tendencies which is not desirable in a formed part.

How much aluminum is in a drink can?

This sheet is typically alloy 3104-H19 or 3004-H19, which is aluminum with about 1% manganese and 1% magnesium to give it strength and formability.


Is steel the same as sheet metal?

No, steel is a specific type of metal alloy that contains iron and carbon, while sheet metal is a form of metal that is produced as thin, flat pieces. Steel can be made into sheet metal, but not all sheet metal is made of steel.


Is aluminum sheet metal magnetic?

No, aluminum sheet metal is not magnetic.


What is sheet metal made out of and is it magnetic?

Sheet metal refers to how the metal is layed out rather than what type of metal. So therefore sheet metal can be made out of metals such as gold, brass, copper and steel. If the type of metal used is magnetic then so is the sheet metal.


What is the function of the sheet metal?

A sheet metal brake is useful for a sheet metal machine. You need a brake on the machine that helps to bend the metal into the correct angle that you wish to bend it.
