When metal is bent, it stretches. Therefore, the flat pattern must be slightly smaller than the finished part. The pattern will also locate the center of each bend, because a typical bending machine (called a BRAKE) will press into the center of the bend area on the "bend line". The reason metal stretches during bending is this. Although the inside of the bend gets compressed while the outside gets stretched, metals are stronger in compression. Therefore, the stretching effect overcomes the compressing effect by a bit. If the stretching and compressing were equal, the flat pattern coefficient "k" would be 0.5, meaning that a line at half the thickness of the material would represent an accurate flat pattern. A typical "k" number for steel would be something like 0.45, meaning that the flat pattern lengths can be found with a line that is 45% from the inside edge of the bend.
Sheet metal thickness can be determined by measuring it. Several specialty tools are available to tell how thing the sheet metal is in actual measurement or by guage, a form of measurement that is used for various types of sheet metal thickness.
The blank size of sheet metal can be calculated using the bend allowance. This number is based on the metal thickness and the tool radius in the brake.
I believe you want to know the MINIMUM bending radius of sheet metal. The maximum bend would be 180 degrees.
Firstly, design and plan based on the needs and requirements of the product. This includes determining the size, shape, structure, and function of the product. According to design requirements, select appropriate sheet metal materials, such as steel plates, aluminum plates, etc. Then, according to the size requirements of the product, cut and organize the materials, and prepare the required sheet materials. According to the design drawings, use sheet metal processing tools and equipment for processing. The processing process can include the following steps: Using equipment such as presses and presses, the sheet metal is formed into the desired shape and structure through operations such as punching, bending, and stretching. Use a bending machine or bending mold to bend the sheet metal to the desired angle and shape. Use equipment such as shearing machines and cutting machines to cut and cut the sheet metal to obtain the required size and shape. Use welding equipment or bolts and other connectors to weld or connect different sheet metal components and assemble them into a complete product. Surface treatment of sheet metal products, such as spraying, electroplating, polishing, etc., to improve the aesthetics and corrosion resistance of the product. Inspect and control the quality of manufactured sheet metal products to ensure that they meet design requirements and standards. After completing all processing and inspection, the sheet metal products are packaged and marked, ready for delivery to customers or further use.
All of those qualities are relative. Aluminum is a good start. For formed sheet metal, type 5052-H32 is pretty common.

It depends on what you are attaching to the sheet metal. Are you screwing together two layers of sheet metal? Or are you attaching a wooden block, for example, to the sheet metal? metal frame to the sheet metal
A sheet metal bender is typically used for metalworking. A sheet metal bender allows the bending of sheet metal. There are many different kinds of sheet metal bending for use in many areas.

Ice melting -putting a sheet of hot metal into cold water.
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.
Sheet metal can be made of different materials. It is called sheet metal because of its shape which is thin and flat.
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.
It is the amount of fire a sheet metal can withstand.

Large sheet metal operations used central computers to direct all sheet metal-forming operations.
