Sheet Metal Materials

Sheet metal is a widely used form of raw material, usually 0.006 and 0.25 inches thick sheet used in sheet metal fabrication. Use the sheet metal gauge chart on our site to designate the thickness. Here are some popular sheet metal materials, stainless steel grade 304 is one of the most common options due to its good corrosion resistance, formability and weldability. If your applications are pumps, valves, chemical equipment, and marine product, grade 316 is recommended. For aluminum, the four most common aluminum grades available as sheet metal are 1100-H14, 3003-H14, 5052-H32, and 6061-T6. Brass is also widely used in the sheet metal fabrication process, it has more strength, corrosion resistance, and formability when compared to copper while retaining its conductivity.

  • Aluminum: Al 5052, 6061
  • Copper: C101, C110, brass (C260)
  • Stainless Steel: SS 301, 304, 316/316L
  • Steel: low carbon steel

What is Sheet Metal Fabrication?

Sheet metal fabrication involves a set of manufacturing processes of forming either prototypes or end-use parts from sheet metal. Cutting, bending and punching are commonly used. So typical tools used in sheet metal fabrication including brakes, punches and dies. The type of machine used depending on the material, the gauge of the sheet, and other factors. Most sheet metal components require a combination of forming processes, but this will not increase the price greatly. The 3D CAD design will be converted into a special machine code, which controls the machine to execute cutting operation precisely and fabricate the final part. Sheet metal parts are known for their durability and economics, which makes them the perfect choice for lots of end-use applications.

How Does Sheet Metal Fabrication Work?

The common sheet metal fabrication process starts with material removal, during the stage, the raw material is cut to the desired shape by different cutting tools. A variety of subtractive machining processes can complete the operation. The second stage of sheet metal fabrication is material deformation. The piece that has been cut needs to be formed into a 3D shape with the forming process like bending. No materials are removed during the stage. The last step is to assembly several pieces into a complete product if there are multiple parts. Sometimes, surface treatment is needed to provide a better surface finish.

What is a Sheet Metal Prototype?

A sheet metal prototype is an early sample, model, or release of a metallic product used to test a concept or process. Rapid sheet metal prototyping service develop prototypes based on designs submitted by customers and test the product before it enters the market. This can minimize the loss and reduce the risk. Various sheet metal prototyping processes at Junying can design your orders in hours and suit your varying needs.

Advantages of Sheet Metal Fabrication

  • High malleability and durability to withstand pressures and last a long time
  • Reduced tooling time to cut or bend the metal, save on the production cost
  • Easy to handle custom simple or complex projects, whether prototypes or large scale
  • Standard sheet metal thickness used in laser cutting or bending
  • Inexpensive but high-quality end-use sheet metal products
  • Improved construction quality, easier to maintain
  • Sheet metals can be formed into virtually any desired shape
  • Sheet metal parts are recyclable and not harmful to the environment
  • High strength and high resistance to corrosion, sun, and moisture
