Sheet Metal Fabrication Materials
Aluminum
Aluminum is a superior metal in terms of strength-to-weight ratio. It offers High Machinability, ductility, and thermal & electrical conductivity. Parts with aluminum also become highly resistant to corrosion.
Subtypes: 5052, 5083, 6061, 6082
Brass
Golden shiny color, low friction, excellent Machinability, and high electrical & thermal conductivity. Brass can be easily machined and the best choice for low-friction applications.
Subtypes: C360, H59, H62
Copper
It offers good strength, hardness, and excellent corrosion resistance with superior heat and thermal conductivity. It also has a very appealing aesthetic.
Subtypes: 101, C110
Steel
High mechanical strength, toughness, resistance to wear and fatigue, and sturdiness. In addition to carbon, other alloying elements can be added depending on the needed mechanical and physical qualities.
Subtypes: 1018, SPCC
Stainless Steel
High mechanical strength, Thermal, Wear, and Corrosion resistance. Stainless steel is low-cost and can be machined easily. Parts made from Stainless steel are durable and do not lose that strength over time.
Subtypes: 301, 304, 316
Finishing Options
We provide various surface finish options. If your required surface treatment is not listed below, feel free to contact us for more options.
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.
Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.

What is Sheet Metal Fabrication?
Sheet metal fabrication is converting the metal sheet into the desired shape. The process involves more than one step while manipulating the sheet metal to form the body, such as cutting, bending, welding, surface treatment, and many more, depending upon the complexity of the required shape.
The fabrication of sheet metal begins with drawings (2D& 3D). However, before starting the actual fabrication, manufacturers develop a 3D such as a CAD file. The 3D of desire shape provides guidance on what actions should be made, which strategy is the most appropriate and practical, which manufacturing steps are needed, and many other things.
Advantages
• Sheet metal fabrication is the low-cost and effective approach for prototype development and large-scale production.
• The finished part or product made of sheet metal has a high strength-to-weight ratio.
• Sheet metal fabrication offers a wide range of material options to create the desired shape.
Fabrication Steps
The steps of sheet metal fabrication begin with preparing a complete blueprint of required parts. For example, it might be the paper drawing or CAD-3D containing all dimensions. Then, it requires identifying the manufacturing steps such as cutting, bending, welding, assembly, & surface treatment.
Cutting the sheet metal is the step where the actual fabrication starts. Cutting the sheet metal into pieces as the dimension in the drawing can be achieved with various approaches such as CNC cutting, Laser cutting, and Water-jet cutting. After the Cutting operations, the cutting pieces need to be joined to form the shape with Riveting & welding. Other processes, such as bending and turning, are involved if angular or complex shapes are required. If holes are present in the shape, punching or drilling operations are used to create them.
Assembly of components is done to produce the desired shape according to the design of parts or products. Last but not least, surface finishing procedures, including plating, deburring, powder coating, or painting, must be carried out.
Applications
Several industries use sheet metal fabrication processes to create parts and the final product.
