The best grades of steel to use for this process are SPCC SECC SGCC Q235 and S45C.

Copper

Copper is a good metal for sheet metal fabrication because it has the ductility and malleability required. Copper is also a metal that has excellent heat and electrical conductivity. It's the best choice for products that require high levels of conduction. The C1100 grade of copper is widely used in the sheet metal industry due to its antibacterial and biostatic properties.

Brass

Brass is highly malleable and spark- and wear-resistant. It also has excellent electrical conductivity. Low friction makes it a desirable material for many purposes. C28000 and C27400 brass grades are perfect for sheet metal fabrication.

Sheet Metal Fabrication Surface Treatment

Name	Description	Materials	Color	Texture
As-machined	Our standard finish for parts is called "as machined" finish. This type of finish has a surface roughness of Ra 3.2 μm (126 μim), and all sharp edges are removed and parts are deburred. You may notice visible tool marks on the surface. Please note that this finish meets the requirements specified for non-cosmetic availability.	All materials	N/A	Stain
Anodizing	Anodizing increases corrosion resistance, wear resistance, and hardness while maintaining the surface of the metal.	Aluminum	Gold, blue, clear, black, red, grey	Matte smooth finish
Bead Blasting	The surface of the parts or product is left with a matte finish. It is mainly used for aesthetic purposes.	Steel, Stainless steel, Aluminum, ABS	N/A	Matte
Brushing	In this surface-treatment technique, rough belts are utilized to leave marks on a material's surface. This is typically done for aesthetic reasons.	Steel, Stainless Steel, Aluminum, Brass, Copper	N/A	Satin
Electroplating	This includes decorative and functional options. Electroplating is another example, as it is a way to manipulate properties using electrical tools.	Stainless Steel, Steel, Aluminum	Black, Grey, Clear, Gold, Blue, Red	Glossy, smooth finish
Polishing	Polishing is the process of giving an object a shiny, smooth surface by rubbing it or using chemicals.	Steel, Brass, Stainless Steel, Aluminum	N/A	Glossy
Powder Coating	Powder coatings use a free-flowing, dry powder. Electrostatically applied powder coatings are then hardened with heat or UV.	Steel, Stainless Steel, Aluminum	Black, Pantone number, or RAL code	Semi-glossy or glossy
Painting	Die castings can be painted with various coatings for specific color, texture or protective properties. Paint finishes range from basic painting to more advanced techniques such as electrostatic painting or dipping.	Aluminum, Stainless Steel, Steel	Black, any RAL code or Pantone number	Semi-glossy or glossy
Chrome Plating	Chrome plating is the process of depositing a thin layer of chromium on the surface of die castings by electroplating.

FAQs

1What are the advantages of sheet metal processing?

Sheet metal fabrication offers several advantages. Cost-effective mass production is possible thanks to the ability to process multiple sheets simultaneously. It also offers high strength and durability, making it suitable for structural components. Additionally, sheet metal fabrication allows precise customization and provides good electrical and thermal conductivity.

2 What technologies are used in sheet metal processing?

Sheet metal fabrication involves several techniques such as cutting, bending, welding and assembling. Common cutting methods include laser cutting, plasma cutting and water jet cutting. Bending is done with a press brake or other bending machine. Welding techniques such as MIG, TIG or spot welding are used to join metal sheets together. Finally, assembly involves joining disparate metal parts, usually using nuts, bolts or adhesives.

3What is the difference between sheet metal processing and machining?

Sheet metal fabrication and machining are two different processes. Sheet metal fabrication involves shaping sheet metal, while machining involves removing material from a solid block to obtain the desired shape. Machining is typically used to produce more complex and detailed parts, while sheet metal fabrication is better suited for creating larger structures and assemblies.

4How accurate is the sheet metal fabrication?

Sheet metal fabrication can achieve high precision, depending on the technology and equipment chosen. Laser cutting, for example, offers exceptional precision, with tolerances as small as a few thousandths of an inch. However, overall accuracy may also depend on factors such as thickness and the type of material used.

5What factors should be considered in sheet metal processing design?

Design considerations in sheet metal fabrication include the strength, thickness, and bend radius of the material. It is important to avoid sharp corners or angles that could weaken the structure, and designers should allow adequate clearance for assembly. Sheet metal fabrication also requires careful attention to tolerances to ensure proper fit and function.
